Poor service once again. Boo you Vodacom

I'm currently a decently long term client. I upgraded at the start of this year. Once again I'm belong over charged.

Contract that I signed for was for around R600, heat I'm being charged over R1050 each month!

Once again pathetic service, I have spoken to the manager/vodacom rep that signed the forms with me and constant excuses of feedback to be given at a later date. I have all communication as well. I expect this to be dealt with timeously.
