OVER BILLING

Good day<br> i upgraded a contract at Maponya Mall 2 months ago and specifically told him to make sure that the i get a R100 airtime on the phone as i've always been on that plan not more as the phone is used by my 18 year old. He agreed and told me it's done<br> <br> Now last month a deduction of R1200 went through again this month it's for R3777 when i callled this morning at 9am i was told that it was not loaded on the system acknowledging that it's his error as they were busy with stock taking.<br> <br> since its his error on his side am i liable for that payment and now i am unable to get through to Maponya Mall.<br> <br> I won't pay that money as it is not my mistake and he did say that the fault was his from his side for not loading as per instructions.<br>
