authenticity of invoice questionable

<p>About 24mnths ago I took a contract with Vodacom which was meant to come to an end on 16/17 April 2016. To make sure it wasn't extended, a few months ahead of the end date I contacted Vodacom to confirm termination at the end of the contract period. I even went to into the shop and was informed the notice was reflected on the system. Wanting to be sure that there would be no further debits off my account, they confirmed the last invoice would be the one for April. In the meantime, I realized that my latest invoice reflected someone else's address, I queried this as well as the authenticity of the invoice content via email but received no response. On further investigation I noticed that this wasn’t the only invoice with someone else’ details.</p> <p>Whilst my contract technically came to an end on 16/17 April I had been told that I would be invoiced until the end of the month and that I needed to remove my sim card (on 29 April) from my phone for 24hrs to have it reset to prepaid. On the 29th I did as was advised. Came the next cycle, I checked my phone balance and noticed that Vodacom had once again loaded data, minutes, SMS as per expired contract terms. When I went into my Vodacom online profile I also noticed that an invoice for May had been raised..now I had two invoices to pay April and May’s. I queried both (May invoice and units) with Vodacom and days later data, minutes, SMS were removed...I had made it a point not to use any as I wasn’t prepared to pay for any. The consultant that I had spoken with promised to escalate the matter to ensure I wasn't charged for the out of contract data/min/sim...no feedback was received from her/superior except for the removal of the units.</p> <p>Vodacom has since emailed me an invoice for May which I'm of the view it is for the additional units they loaded in error and later reversed, which is therefore not my liability. I would like for them to review my account from month one given that some of my invoices reflect details of someone else - for all I know I could have been charged for someone else’ services.</p> <p> </p>
