OPERATION AND REPAIR OF BOILERS

The problem is that I bought this long ago washing machine Indesite wise107s and bought another daughter for my daughter. top panels the bottom on the sides is not peeled off nicely. Now, if the manufacturers thought that many people complain about the painting of the car. Invented a good painting, then nothing else needs to be invented. The model would be better. Can't compare with the indesite of Ukrainian manufacturers. You could trade one This model. People know that she is super, I don’t need another. I would have bought the same one, but unfortunately it was removed from production. It's very bad, I don’t want another model, I don’t want even a better one. I already know it. But I bought my daughter from the bay of a flounder and it's not that coat. People want to buy, want to spend their money, and manufacturers are in a hurry for different bells and whistles for cars. But we don't need all sorts of cool bells and whistles, in Kharkov the price of electricity is crazy. Soon people with such prices will stop buying altogether It’s enough that we once bought toasters, microwave bread makers, multi-cookers, toasters, coffee makers, now everything is lying around as unnecessary, because the price for electricity is exorbitant, and the wages are pretty penny. e goods are not for us. So if you want people to buy something, you have to do something for this with the prices of the goods, and most importantly with the price of electricity, otherwise all large supermarkets will soon have to be closed, and they will not be profitable. she worked for many years in the Barabashova market. Previously, people bought up heaps of goods, but now they have closed half of the shops. There is no imported goods, but they sell such dreck, they have nothing to buy. No good boots, no good clothes. There is nothing to look at, everyone runs away from the market. in another business. The bazaar is dead, there is nothing to do. So are electronics supermarkets. Do the owners of large stores really do not understand this, because the owners are rich people. then these rich people will try to sell their store or a bunch of goods that have turned into old junk, which no one takes. After all, you can buy everything now without leaving your home. Who needs to buy online and cheaper and do not have to go for three nine lands to burn benz in order to buy household appliances in the supermarket. People are not fools to pay more for renting a store for the salaries of sellers, managers and servants. They will not steal. A good product should cost money, but excuse me not so much as we even sell medicines through fourth hands. For example, a factory abroad produced a good medicine, selling it made money on this medicine. It was bought by wholesalers who brought it to our city, sold it to the warehouse, we also earned money. Then they brought it to the pharmacy, they sold it to us, too. , so pharmacies are now like uncut dogs, at every step. They also sell electrical household goods. Finding something real good now is also a problem. Cigarettes and those are counterfeit, if they grew tobacco, dried it, made cigarettes from it, then already would fly into the pipe and go bankrupt. That tobacco would not grow, then not the harvest, etc. So they need to make money on you. There is no tobacco, and all kinds of grass with additives and flavors. That's all. The owners of the Bentley factory have a three-story mansion. And you have a cough, shortness of breath and lung cancer, to help out the pharmacy business. Remember the film has long been YOU FOR ME, I FOR YOU. Do not help out deceivers with vodka, the same thing, Deshmanov alcohol plus distilled water. And that's all. Durilovka is in everything. People will be vigilant. , oh, how I am all of you x sorry.
