Cell C the worse ever

Customer Service is very very poor at.Cell C. I called to query why a debit order is still going off my bk account after I cancelled the contract on November 2018. After holding on for 30 minutes I was told they cannot help me the call was transferred to the Legal department. After being on hold for a further 15 minutes the call was cut. I tried calling back a few times and after holding on for a period of time I was transferred to Legal and the calls just kept bring cut off. I am so frustrated. All I want to do is resolve the issue with my account. CAN SOME ONE FROM CELL C LEGAL CALL ME PLEASE. ********** 01
