Vodacom is just useless in general

Vodacom is absolutely useless. The signal in our area has been deteriorating the past week and now we can hardly get a proper signal. When we phoned Vodacom this morning, I've been busy trying to get them to log a request to service the tower, just to find out that somebody must have changed something on our profile or it must have happened when they changed our contract from a 350 to 354, So now we have to drive into town to see what is on our profile - at todays fuel prices!!!!!! We also tried to phone 3 of their shops in Witbank but 2 just give "peep-peep-peep" and the other one just keep on ringing with no answer. I have also asked Vodacom numerous times in the past to SERVISE THIS SPECIFIC TOWER REGULARLY because it is smack in the middle of several mines which are blasting a few times daily, but every time that the signal becomes weak - even with boosters in my house - I have to phone again and even then some people say they can't just log a service request and I have to revert to Hellopeter to get any reaction.
