bad service

Tile Africa sold me a shower with 2 parts missing. When I contacted them to find out if they had these 2 parts they said they did. I then asked a friend to drive to collect the parts. I asked the sales person to please wait for my friend to arrive as he may not make it by the time they close. He said he would. My friend got stuck in awful traffic trying to get there. The salesman phone me to find out how far my friend was when the store closed. I gave the salesman my friends number and I also contacted my friend to find out where he was. My friend arrived about 20 minutes later only to find that no one was there. The salesman didn't have the decency to phone myself or my friend to say he was no longer waiting. He was quite happy to leave knowing that a customer was on his way to him. This is the 3rd incident of bad service I've had from this branch. I most certainly will not have anything further to do with this store if I can help it.
