long repair time

I contacted the official service center on September 27 in St. Petersburg, the operator's network stopped working on the iPhone 11 device, s / n: DX***73D, they started watching it only 2 days later on September 29, after it was sent to Moscow, now technical ones work with it Specialists from 09/29, this is 6 days more, and the service center does not say specific terms how long it will last. Please stop this and help solve the problem.
