BAD SERVICE

On the 6th of April I called to cancel my one line with Vodacom. The lady who helped me ended up selling me an ipad. I was told this would be delivered to my house in 3-7 working days. 2 weeks went past and nothing was delivered. I called and was told an upgrade couldn't be done on the phone for an ipad without an order number. I then explained that id rather have aniphone. I have called numerous times and spoken to multiple people to get this issue resolved and nothing seems to have been done. I went into vodacom today and on the system it's saying my line has been upgraded to the ipad. PLEASE CAN SOMEONE HELP ME. How many people do I need to speak to to get this done ? Or who do I need to contact ? The cancellation department doesn't answer and customer care keeps transferring me or saying they'll call me back. I JUST WANT THIS SORTED
