Poor performance and no reception

It is with utmost disgust I am writing this regards to Vodacom utterly poor performance and even worst service. Have been writing emails to Vodacom customer service about poor to no reception at my residence. My wife has also phoned Vodacom on numerous occasions have been promised that they would come out and install a booster for us as we have been with Vodacom for many years. We then get this stupid email asking us for our gps location after they have our address. How stupid can it be to ask that on a open forum and then wonder why burglaries occur???? Have a contract with Vodacom which i will certainly cancel due to non performance clause.
