Still waiting for feedback

i had sent my latest banking statement via email to Tehri Moodley disputing double deduction the amount of R377.49 that was debited twice by your company my argument is that you guys say if 5 debit orders went through that means I was debited correctly but my problem is for Nov alone it cannot be R507.89 as I only started the contract with you guys on 17TH of November 2014 so does that mean for two weeks you guys charged me R507.89?? that doesn't add up and i haven't received any feedback. i dont whether my query is attended to or not and i cant get through to the call centre.
