Cell C - non existent service

I have requested relief from Cell C the first week of May. At this stage my account has already been suspended due to debit order bounce. I have sent all relevant docs as per their requests... however, Cell c themselves gave me incorrect emails to send to. This caused an even bigger delay because no docs were received. From this point on i was unable to get hold of customer services to har a chat with an agent to make arrangements. Dialing 084 135 or 140 let you go through the voice prompts but drops the call as soon as they try to connect you to an agent. This has been like this for months now. I have spoken to an internal gentleman that phoned from collections, whom I explained the situation to and he was very helpful. Unfortunately he does not have the authority to assist in the matter. As a result I've requested he escalate the matter to his superiors In order to resolve this. Ive sent numerous mails, requested numerous call back requests via app and online. My services have been suspended for months yet my bill keeps on increasing every month? Please can you intervene so that they can call me so that i can sort this out with cell c. Thank you
