Disgusted by your actions

I have a data contract with Vodacom that is on a mymeg 3gig promo and I know I receive 3 gigs day and 3 gigs night owl data for R169. Now Vodacom customer services tells me its an open line for R169 and I only get 3 gigs night owl. I never signed for that and I have now a bill of over R400 of which I never signed for. They can't produce the paperwork for this open line where I signed for it all they can do is escalate it. Pathetic service. Last month I phoned for a glitch on the ****le with regards to the balance, sent an email, got no phone call or explanation just a sms to tell me the matter is resolved. For a customer that has been with you for over a decade this blatant ******* disappoints me and I would never recommend anyone to sign up with Vodacom
