Cell C does it again!!

I am hoping you can help me out here. I have sooooo many issues with Cell C right now that I am actually at wits end. Let me start with my R70 saga:

I stopped my debit order and the debit orders still ran... so Cell C charged me R70 for this.... then when I complain etc. I finally get that resolved and Cell C tell me they will credit that amount for me and it will not be on my account. I then receive an sms saying that I am R70 in arrears... again? No one can explain this! I would really appreciate if that can be sorted out as soon as possible.

Then the next issue. I changed my Debit order date, for all 3 accounts to the 7th of every month, so that I can pay the EFT 5 days before and then the debit order wouldn't run. Low and behold... on the 1st of May, the debit order runs. I then ask what is going on, only to be told that someone will contact me - still waiting! Then all of a sudden on the 8th of May the debit order runs again, even thought the payment was made on the 1st???? I EFT'ed the money, like I normally do!!!!!!

Long story short. I am tired of the shear incompetence of Cell C and their lack of customer support. I cannot begin to explain to you how the customer service in the last 19 years has dropped to the worst in any industry. I think I get better customer service form the department of home affairs!
