UPGRADE

i did an online upgrade on my contract at the end of last month. there was an upgrade fee of r150 and a sim card fee of r10. as i have had my account for about 15 years i did not expect anything other than for this to be collected with the next debit. about 2 days after the upgrade i started getting the most irritating voice messages stating i was in arrears and will be cut of. my wife also got these prerecorded messages. i called the call center -on 6 July - REF S3-8AA8N-N5B9 - and agreed that my account would be debited on 8 July. this never happened and the irritating messages continued. today i got a message to state this is my last chance to pay. i called the call center again only to be told i agreed to make a cash payment. clearly not true. i arranged again for the debit to collect the money and asked for a reference number - this could not be provided- and an sms confirming our discussion and the debit will collect the amount - this never came. POOR SERVICE ALL ROUND!
