Poor Service Unauthorized purchases

<br> My edgars account was on a -R30.91 balance after I paid on the 16th of February 2016. On the 17 and 29 of february there were purchases that were made without my authorisation. I called in end of February requesting that the purchases must be reversed and they told me they forwarded to relevant department and there was not feedback given to me. After that I wrote to them on Facebook on the 16th of March 2016 they promised the query will be resolved shortly and they gave me ref number ***/GO. The same purchases were made on 29 March 2016. So instead of resolving my query they are repeating the same mistake. I am not happy about this as it has affected my credit record. I wont pay the balance reflecting as my balance should be still on -R30.91. Service received thus far is poor they keep on transferring me when calling but not one is willing to assist istead they give me email when emailin they promise it will be resolved but it is now more than 35 days still m having the same query.<br>
