Alleged arrears account

I have now been battling for almost a week to speak to somebody in the accounts department as not one of the call centre agents are able to assist me,<br> <br> My cell phone which I purchased through Fonechoice got damaged and got repaired through an insurance claim also through Fonechoice.Finchoice now claims that my account has been placed on hold due to non payment of the excess on the repairs done. In Feb 2015 Finchoice placed my account on hold due to them not deducting the excess of R 200 00 on the repairs. On the 4 March 2015 I went to FNB and deposited the R 200 00 into their account. The hold on my Finchoice was then lifted.<br> <br> End March 2015 Fonechoice ran an additional debit order of a R 100 00 on my account , an upon enquiry I was told that this was for the excess on the repairs of my cell phone. I was then refunded the R 200 00 that I paid cash into their account.<br> <br> Now it is May 2015 and again I am being told that my account is in arrears and that I am a slow payer. This hurts me tremendously as I have never skipped or paid late on any of my Home choice group accounts<br> <br> How do I go about in getting somebody to go into my accounts and sort this problem out ?<br>
