Cell C is *********** their customers

I have 2 contracts with cell c. my one line is a Postpaid Smart Chat 500 MB @ 371.00 monthly subscriptions. The other line i took in September 2015 and it's a 2GB Smart data Package - 24 Months @ R99.00 per month. I received a statement and now my bill is R 1388.58. I called customer service to enquire about the billing. The explanation I got was that my bill is made up of the following:<br> 1. Postpaid Smart Chat 1GB @ R630.70 <br> 2. 2GB Smart data Package - 24 Months October ' 15 of R86.84 <br> 3. 2GB Smart data Package - 24 Months (19/09/2015 - 30/09/2015) pro rata for September R 34.74<br> 4. Connection Fee 19-Sep-15 of R 171.05<br> There's a couple of amounts that they mentioned which i was aware of, which included outgoing calls and additional data that i purchased during the month.<br> My problem is the R 171.00 connection fee that I'm being charged which to my knowledge i paid in store when i took out my second contract and i was told its R195.00 connection fee. Secondly, all of a sudden my Postpaid Smart Chat 500 MB for R 371.per months was billed at R630.70.<br> Cell c is ripping of their customers and they always incorrectly bill their clients and the claim that its an error.
