Unsatisfied Customer

On the 26th October 2024 I lost my phone, i went to claim it because I have insured my phone the beginning of my contract. It has been 2 months now without a phone and I went to call them they keep on saying of my signature is not the same and also those agents are impatient to help the customer. I am not happy with their service, I never skipped my payment at all, been loyal to the company, please help me out
