Cell C did it again

I have been contacting cell c for the past almost 2 years to finalize my contact with them. Nobody seems to be available to assist me as they’ve blocked my SIM card and I just want to settle my account and move on. The service I’ve received has been nothing but disappointing from cell c and I’m embarrassed to see how long I’ve actually been with them. Can someone please contact me I want to settle your account ASAP! Lockdown can’t be the only reason here.
