Vodacom service and loyalty sucks!

We have been on Vodacom contracts for more than 21 years. we stay very close to the CSIR in Pretoria and 3 years ago we started to loose signal at our house. Eventually we reported the problem and they send an technician out to test the signal. he told me that there were definitely a problem and they will look into it. Never received any feedback. In the meanwhile the signal has deteriorate to such an extend that we now have almost zero signal. Me and my wife are both mostly working from home and receive hundreds of calls a week. We are currently loosing a lot of business due to this situation. we have reported it again received an sms stating that the complaint was attended to and resolved because the could not get hold of us. SURPRISE SURPRISE WE DO NOT HAVE SIGNAL!!!!! We now again complained to Vodacom and we were told that we can cancel our contracts. Now I am certain that if I had a client in my business for 21 years i will do my utmost to help where i can. This service really suck!!!!! Now I must take time and trouble to move all the contracts to another service provider!!!! Vodacom your service and loyalty SUCKS!!!!!!
