Account enquiry

My query is related to an administration fee that is levied on accounts for non-payment. Firstly, upon entering into the contract, I do not recall being advised of these charges and secondly, these charges may have been introduced after having my entering into the contract by virtue of the regulations by ICASA, CPA and diminishing margins etc. <br> <br> In this instance, my credit card account has been upgraded by the issuing bank twice in the past two months. Initially these details were updated through the call centre, your details will show this. but I neglected to do so the second time around. I have requested these charges to be waived on principle. In June 2014, my account was debited twice, which I had instantly complained about using this medium. My mobile account remained in credit for this time but the associated charges and admin fees charged by the bank due to Cell C having debited my account twice in error, were not claimed nor requested by myself from Cell C. I have multiple accounts and to have to pay an admin fee for each is infeasible.<br> <br> I request these charges to be waived based on my payment history over the years as a loyal customer of Cell C.
