WRONG INVOICE & DEBIT AMOUNT

Good day<br> <br> I am very upset as I am writing this email. <br> <br> I already had a contract with Telkom Mobile, which my sister is using, and decided to take out another contract in November because of the benefits. The service was not up to scratch because I constantly had to follow up and the phone just rings unanswered which meant that I had to visit the branch frequently.<br> I eventually got the contract and was told that I will get an confirmation email. To date nothing has happened. An invoice was emailed of which the content and initials were wrong, I lodged a call via the 081180 but nothing has still happened. I just keep on getting sms about a case being lodged. Now an sms was sent to my sister's phone stating that I will be billed R667.57!!! Why if my contract is only for R199 p/m & my sisters just over a R100???? And why can't I access my account information on my phone??? I am very disturbed and regret switching from Vodacom to Telkom Mobile. I hope you can resolve this speedily and view this as an urgent matter. I await your response.
