the theme is old, but if anyone will be the same — unfortunately, the service, saying "I not I, and not my horse" in General is right :(
Service centers in Russia do not bear any responsibility with rare exceptions (Bosch — but they are just to prescribe the full responsibility of ASTs in the contract warranty service). In Zozpp is 23.1 liability "of the manufacturer, the authorized organization or authorized individual entrepreneur, importer" — ASTs in 99.99% is not anyone from the list (except if the ASC takes the responsibility in the contract for warranty lack. But there are also need to consider the honesty of this office.
For example, Dixie Service writes about such liability, but if the case goes to claims(e.g., refund), it appears that with the counter sold you the machine they did not work, and you do the scammer — you have printed this busaiku). In fact, in case of a warranty claim, they're such a third party are responsible not to you, but only to a firm which has a contract with them for service.
I will say even more — for example if you buy something from a seller in Russia, and you will be referred to the ASC with all claim — ignore it. Attributed to fix. But all claims (refunds, all spoofing, etc.) should go to the seller. If you take it to ASC, then legally you gave it to a third-party firm which does not bear any responsibility to you.
