Failing to deliver as contracted agreement

I upgraded my contract with Altech Autopage. I was given a new package different from the previous one I had. Nelisha the consultant said I must call Autopage customer care on the 10th February to activate my new account, which I did. But fistly my debit order was suppose to be R 414 but went to R537.12 and I phoned them and was promised a refund. Secondly my package includes 300mb and 100 sms but that is not active. Last time I mantioned that to Autopage they said they will charge me more. Please help
