Vodacom signal dead or weak in Sandton

This is a recurring problem - for most of this week, I had no signal while working in Sandton (Maude St and Fredman Dr vicinity).
Please Vodacom, sort this out. I'm missing 80% of my incoming calls and this is unacceptable (since I pay 100% of my account, I expect 100% service).
My next move will not be a complaint, but a move to one of your competitors.
