Unbelievably bad service

On 10rd April I had to call 8 times to ask that my softlock be removed i can't begin to explain the frustration I've been experiencing with Vodacom lately. For some reason my data usage is hitting the roof, very bad reception in my area and delayed service. I have never had these issues before but lately its getting worst. I am considering changing service providers because this is pathetic!!!!!! Someone needs to contact me urgently regarding this matter.
