Bad bad service and *********** staff at Vodacom

I have never in my life been so frustrated dealt with such unprofessional *********** people. Justin from Likeminds contacted me for and upgrade on 5 contracts I have with Vodacom. From day one I had problems with the whole upgrade process. He quoted totally different amounts, than what is debited to my account now. Withheld crucial information in selling these upgrades. I spend hours on the phone to get hold of him or a supervisor. No luck. I spoke to a list of people as long as an a4 paper to get answers. No luck. The delivery address for the new devises was messed up. The list of problems goes on and on!!! What more must I do to get answers or help with my query. Phoning Vodacom does not help. I've had it!
