Billed For Lapsed Cell Phone Insurance

I reversed a D/O in April 2015 as i wasn't aware it was for my cell phone insurance with Cell C,was surprised to see the same amount of R119 going off my account on the 25 May and made a follow up who was debiting me,I called the call center and was advised that my insurance has lapsed although no double debit was done in my account due to the reversal I made in April as my contract states that I'll be given a 30 days grace period before cancellation and was told to send POP which I did on the 3rd June to [Email Removed] however no one came back to me.<br> I called again on the 06/06/2015 and was advised the matter was given to a supervisor by the name of Buhle to escalate,It's the 17th today and no one has bothered to give me feedback.<br> <br> Can I please get my money back if my insurance is not going to be reinstated,how can you tell me that double debit couldn't be done because no authorization was given where else the single debit collected successfully.If only the call center agents answered the calls non of this would have happened in the 1st place ,one has to literally hold on the line for more than 30 minutes until you hang up.
