Vodacom pathetic

Its been more than 6 months and vodacom has not resolved the whole signal issue in Genadendal. After 7pm no ones data works and data signal switches off randomly during the day. Everyones phones show full bars with hsdpa+ but connot connect to internet. I tried to log a coverage issue yesterday and consultant promised he would. I asked for a ref no but his reply was I would get it once I hung up the phone via sms. This never came so I am gathering he never logged this issue. How can Vodacom be so lazy with regards to this. Its untterly pathetic.
