DISASTER, DISASTER!!!!!! HUNG UP ON ME TWICE

I have a 24 months data contract with Cell C which expired on September 2019. No sms or calls from them to let me know that my contract is coming to an end (after all they have a system to track such things). Yesterday I called after seeing a bill of R320 from them. The first ‘’consultant’’ I spoke to; I requested my contract and all statements. She only sent me few statements. She then forwarded me to the retention department. The 2nd ‘’consultant’’ that I spoke to didn’t help me and assured me that her supervisor or manager would call me back but dololo. A couple of hours later I called again the retention department, I told the ‘’consultant’’ that I want to cancel my contract with them and want this month to be the last month that they debit from my account. She told me about the 30 days’ notice and I informed her that no one called to inform me about my contract expiring and requested to talk to a manager or supervisor, DEEP BREATH! SHE HUNG UP ON ME. I called back a few minutes later and articulated the same story to another ‘’consultant’’. After putting me on hold for 25 min or so she informed me that her supervisor will give me a call. I’M STILL WAITING. Today at 11h44, I received a call from Cell C with regards to my contract request and the ‘’consultant’’ said she will forward me the contract, I’M STILL WAITING. She inform me that she will put me through to retention department again and SHE HUNG UP ON ME.
