Rediculous signal and service

Poor signal, poor service, no resolve on any of the matters we phone in for. I phoned in about 6 times in a month seeing that we pay for services but receive very very poor service and signal. Then Vodacom blocked me and I had to phone from another phone to get hold of them. They then said we phone them too much with complaints thats why they blocked us. How is it that Vodacom blocks their 10 years plus, paying clients because of complaints but dont resolve any issues. Thats outrageous ! Vodacom needs to contact me and solve these issues 'cos I also record every converstaion and I will be taking them to court very soon.
