Did you manage to solve the problem? It is not clear why the operator torments you so much if he is not going to unlock your phone anyway. My phone was also blocked by the operator, and they immediately told me that they would not unlock my phone while there was a debt. However, I wanted to change the operator and decided to find another way to do it. Then, on the advice of a friend, I turned to
priorityunlock.com to unlock the phone. The problem was solved very quickly, and I changed the operator. Several months have already passed, there are no problems, the weight is working. Well, you can solve your problem in the same way.
