Dissatisfied Cell C client

I have had a terrible experience with Cell C and their *********** staff. They have be debiting my account and not reimbursing me for the double debits despite my request. Cell C does not value their clients and the staff is rude and impatient. The last lady i spoke to blew her frustration into the microphone and dropped the line. I feel like giving back this sim cards as it is causing more havoc then anything else
