Worst service we have ever experienced!

I am writing this on behalf of my boyfriend. He bought a Samsung phone from Vodacom and within days he realised that the battery was only lasting half a day. He then took it back but because it was not within the 7 day refund period it was sent away for repairs. It has been months now and the phone has been sent away for repairs multiple times but nothing has changed. Every time we go in to Vodacom they pass us on to someone else. He went to Canal Walk Vodacom again today and he had to wait an hour for someone to help him. And yet again the phone has been sent to Joburg to be repaired. This is unacceptable! He paid a lot of money for the phone and should have been given a refund or a new phone months ago. I also called the Vodacom call centre today and all they did was refer me to Samsung. This whole process has been ridiculous. He works all day and has made so much effort to get this matter resolved but nothing has been done. It doesn't even look like the phone has been repaired. The way you have treated us is unacceptable. If his phone comes back in the same condition we will demand a refund. Enough is enough! And we definitely won't be spending anymore of our hard earned money at Vodacom again!
