Sales person incompetend

Hi my GF went to MTN Eikastad to migrate her MTN topup to contract to mychoice 100 for R229. Then Owen could migrate said there was a problem. She had to go back later he gave her a cheaper option for R189.<br> Didnt explain to her she wont be getting 100min but R100 airtime? Thats a totally different contract. Since then its been a uphill battle. Owen does not want to except his error. I phoned Owen and told me the contract can only be migrated after 3months and he will contact me to process it. Well he didnt. Nobody except Eikestad can change her contract to the right one. I then went and actived Datashare on my Data contract. We went at Paarl MTN and the sales person linked het number to my Data with a reference number *** and we both recieved sms's that it was activated and should be active in 48hours. Still she got Datacharges? Owen tell me thats not a MTn reference number even though the mtn printed it out for me? Ive sent a couple of emails about the datashare and only response is i must phone the customer care. Why do MTN have a email complaints adress? I would apreciate if someone could respond this from MTN.
