Suprise fees and no after sales care.

If you know what's good for you stay away from Cell C. I was called by a Cell C call centre Jerome Haminah on the 18 October, he sold me the data contract for 20 GB anytime and 20GB. The agreed debit date was the 28th, I woke up this morning (25th) they debited my account, for what God knows. I called this morning spoke to Gugu Mnchunu, she said this was a testing debit to see if my account works. This was the 1st time I hear about this testing debit. Why was it done on the 25th yet my debit day was 28th. When I ask Gugu to transfer me to her supervisor or someone who can assist me with my complaint, she told me to send an email. Now why do I have to send an email when I have a problem, yet I was called when they were selling me the product. I am very upset!!!
