Mis-Information & Incorrect Charging

I am at my wits end and drowing in reference numbers - I will start with the current issue - on the 14/01/15 on going to Pav to once again raise the data charges issue, I was kindly advised by the consultant to amend the paid up contract from Cell C All Week 100 to the Straight up 100 Top Up, as the call price is cheaper and you get 100mins, 100sms, 100data per month - I confirmed at the time, no additional charges would apply, and that the contract is to remain as paid up and on a month to month at R100+BIS.<br> Imagine my fury on reciept of the February Billing, reflecting R174.56 (excl vat) (R199incl) - a quick search of the internet reveals this package at R100. I phoned and then went to Pav where Sumaya is adament that the cost is R199 and that the Straight up 100 Topup-DEVICE is purely the package name and is correct, despite 3 other staff agreeing that the fee should be R100 as no contract renewal or device was taken out, simply a change is package! (REF582360)<br> Since Sep Inv 2014, we have been getting Data Charges billed on this paid up contract as well, despite having BIS and never incurring charges before-3 cr recieved, 3 still outstanding *** (latest) total R165.59!
