uChoose Smart M

Found out today after having my new uChoose Smart M account for more than a year that I have been paying for 120minutes a month airtime and only receiving 60minutes (My own fault for not checking my online account earlier I suppose). I am completed disgusted with Vodacom for basically *****ing for I don't know how long. I have spoken to the call centre and the consultant keeps asking me when I have topped up. I have explained that I never top up my airtime as this is not necessary. I supposedly get 120minutes a month and this is more than enough for me. He was not able to help me and I have asked to speak to a manager. I have now been on hold for the last 20 minutes and no one is answering. I only found out by accident as my airtime ran out today and when I checked my account online is said I have 0min of 60min. WHAT!!!!!???? After this contracts expires I will not renew my contract with Vodacom. Totally disgusted!!!
