Solving technical and other issues on home Internet from Rostelecom

Question

Computer networks

Good evening. Unfortunately, I don't have the opportunity to ask on the company's blog, so I'll ask here.
Is it possible to find a person from Rostelecom who will help in solving my problems that numerous telephone services cannot cope with?
Problem 1 - DHCP settings are constantly reset on the ONT terminal installed in the apartment. It is obvious that they come from a communication center. Unfortunately, technical support, being unable to understand the structure of their network, sends me to the subscriber department.
Problem 2 - a request for recalculation for an erroneous write-off has been hanging for 3 months. "Letters of happiness" regularly come with a demand to pay off the debt. There are also no moves.

Answer 1

Certainly not a solution, but I would consider changing the provider, with such and such maintenance.

Answer 2

Unfortunately, there are no other options for a backup line.

Answer 3

On the 2nd point, go to the subscriber department with legs and figure it out. And preferably not close to home, but to the central / head office. In our city, Volgograd, Rostelecom, this is the former YuTK, and more rummaging around at the head office

Answer 4

I will go to the subscriber department only in case of termination of the contract. There is a fundamental desire to understand it remotely. Moreover, I already submitted the first application there.
