Terrible Service if ANY at all

I took my phone in for repairs on Tuesday 8 August. I was told that I'd be phoned for the quote, but by Friday no one had phoned so I went to the shop. They generated the quote for me and I immediately paid. A week later I went back to enquire as to the progress and was told that the quote was yet to be accepted and paid. This was corrected. I have since been to the shop 9 times. I have gotten my phone back twice and both times absolutely nothing has been done to fix it. The staff also keep 'giving their word' that they'll phone me once the phone is ready for collection, or at least let me know what's happening. They don't - they are completely incapable or uninterested in providing feedback. If you want the number of the manager (Charlotte) they are happy to give this to you - the number is however diverted to the shop which gets you nowhere. Now, more than a month later they are apparently waiting on a part before repairs can be done. Interestingly though, the part they are waiting on is for an antenna cable as my phone no longer picks up networks. This was not a problem when I handed the phone in for repairs. I merely wanted my screen replaced. Now I realize the Service Department is completely separate from the Sales Department, but I feel sorry for Chantel and/or Kurt at the Tyger Valley branch. In November I need to furnish an entire kitchen (fridge, washing machine, dishwasher, extractor fan, microwave) as well as buy a 55" telly and there is no way I'll be buying Samsung. So those two have lost a pretty good commission. But why should I support Samsung if they do not care about their clients through after-sales service?
