Terrible customer service!!

Been a loyal customer for over 15 years and I’m utterly disappointed with their poor customer service. A contract upgrade has been *****ulently done on my account and I’ve reported it to the ***** line the minute I became aware of it in July 2025. Submitted all the necessary documents and have received zero response. I have been calling them every couple of days since and have been sent back and forth between the ***** and accounts department without any success. My account was suspended a couple of weeks ago even though I had to go in-store to pay my monthly account after my debit order was stopped by them. Today I phoned both the accounts and ***** department again, I was informed that the matter was resolved as the documents I submitted in 2022 when I upgraded and the documents I submitted when I reported the case i.e. my ID, was the same?!? My mind was blown🤦🏽♂️ Now I’ve been told that I have to open a case with SAPS, all the while my account is not much higher than it ever was or supposed to be with this upgrade.
