Billing, Feedback, Accounts

I am really disappointed with MRP Mobile after their launch they called me to offer a contract, which when the conversation was about to finish they realised that they cannot give me the contract because it is my husband who has an account with them and they called him to tell him I am interested in the phone that they were offering. they arranged with him and delivered the phone . On the 15 December 2015 a debit of R114.13 went through my husbands account but they had said the phone contract is R70 and R30 for service fees which we thought it was reasonable but now the debit order was not what they had agreed on. on the 18.12.15 another debit order R138 ,R49, R49, R49, R39, R39 and on 18.12.15 my husband called the call centre to enquire about multiple debits and spoke to a lady called Cindy who promised to call him back in 3 days until today that 3 days has not passed / they are confused about the 3 days. We are not using their sim card and they keep billing us with no explanations right now we want them to take their phone and sim card and leave us in peace. The level of their unprofessionalism is beyond me. we don't want their contract anymore.
