Double account charges- horrible service

I migrated/upgraded my data contract at the Kenilworth Telkom store, <br> I was advise that because I am upgrading to a higher package there would be no additional charges.<br> <br> After checking my account online, there where now two contracts running simultaneously, this is now the 2nd month that this is going on for.<br> <br> I went into the Kenilworth store again, I was told that this is normal and the 1st contract would close after the 1st month.<br> <br> I then received my invoice, which showed both contracts being charged, i.e. the 1st contract was not cancelled.<br> <br> Both contracts charges have now come off my account (contract 1 * 1 month + contract 2 *1.5months (prorata of initial month included).<br> <br> I have enquired this with the Kenilworth, Claremont and Canal Walk stores, all useless! no help at all, no-one has the power to check resolve the problem! <br> <br> Telkom sales persons are useless at resolving problems.<br> Telkom is useless at responding to problems
