Non existent service

On Wednesday, 18 March my husband and I went from our home in southern suburbs to N1City branch of Neotel to sort/upgrade our existing contract with Neotel. We were promised that a technician would phone to make a time to come to our home within 5 days. No phone call or technician arrived. Phoning the N1 city branch only gets you to an answering service, you leave a message( which we did at least 5 times) and NO ONE COMES BACK TO YOU! We returned to the branch on Thursday 26 March where we were told that a technician would phone on Monday 30 March to tell us what time on that day they would be coming. We were given Dale Williams telephone number to call in case of problems. A lady phoned from their technical branch on Monday morning to say that they had an opening on that coming Wednesday! We explained that we had been told someone would come that day as we were not able to be home from work on the Wednesday, she would phone us back. Nothing! Tried contacting Dale Williams twice - no reponse back either. We stayed in the whole day waiting for calls back -nothing !I'm on the verge of cancelling my contract all together let alone upgrading it. The worst service ever received!
