A service warranty is good when you have not completed the warranty period to repair your equipment, but after that, it does not work. It is faster and easier to contact other repair offices than wait in line. I encountered this when my dishwasher broke down, and the official service told me to wait 7 days for a specialist to come to me. I didn’t want to wait and find guys who make dishwasher repair much faster, and most importantly, just as professionally and at an adequate price. And two days later, I had the parts replaced and given a guarantee for their repair. The list of household appliances they repair is very large, and I think it will be useful to many.
