Terrible Conduct of Business

I app**** online for my contract upgrade on the 9th of February, this was just the beginning of the problems I have encountered with Vodacom. Firstly, the phone I wanted was out of stock so I had to wait which was understandable. I only received my phone the following Monday (16th Feb) after being informed I would receive it on Friday (13th Feb) When I get my NEW phone it was faulty - so I was of course unable to use it. I contacted customer service on Tuesday and enquired about the process to follow. I was told someone would call me back immediately - no one did. I had to phone back 4 times to get an answer. I was informed that they would have the phone collected and taken back to their warehouse and only AFTER it reached them would I be able to reapply for a new contract, and it will take 7-10 working days for the phone to be collected. Baring in mind that I received a \dead on arrival"device. I have been a customer of Vodacom's for many years and I have never encountered such terrible service. Why should I have to wait this long when Vodacom is actually at fault? Some feedback would be appreciated. """
