Promise to be apply correct credits not fulfulled

Since Dec14 my account was charged with R79.00 for My Credit bundle (for which I never requested),and R59.00 for BIS for a Samsung S5 device. Both costs continued until July 2015 accruing to an overcharged amount of R1104.00. To date only an amount of R450.64 was credited to the account. A balance of R653.36 still needs to credited to the account, I have been in contact Autopage since July 2015, but the matter remains unresolved. I demand that the credit be processed immediately!!!
