Vodacom make mistake and I have to suffer

On 2015-02-11 I received my monthly statement and noticed an additional amount for a handset on my statement. I called Vodacom customer care who informed me that I have upgraded and received an I-phone. They informed me that someone have upgraded and changed the contract and if it was no me they advised me to open a ***** case and they will block my account till the matter is resolved. How can they allow someone too upgrade and change my contract?<br> <br> I opened the case and forwarded all the required documents to Vodacom on 2015-02-11 and received confirmation that it was received on 2015/02/11.<br> <br> I have follow-up on this case on:<br> 16/02<br> 23/02<br> 26/02<br> On 01/03 my debit order still was deducted.<br> 03/03<br> 05/03<br> 09/03<br> 10/03<br> 12/03<br> 16/03<br> 24/03<br> Up till today the only feedback I got was that I didn't submit the required document, which I then resent 4minutes after receiving the e-mail.<br> <br> My problem is:<br> Vodacom made the mistake .<br> They that their time to resolve the problem<br> But I have to pay my monthly costs even though I don't have any service or internet usage.<br> <br> Why must I as the client carry the costs and suffer while the BIG AND MIGHTY VODACOM makes a mistake.<br> <br>
