incorrect info and no follow ups

last wednesday i called in to customer care to have a my vodacom application sorted out due to having an old number no longer in use attached to it. the guy who logged the call was very helpful and said someone would call me within 24 hrs or sms with the outcome. to date that hasnt happend. calling in again friday i was told that the case would be resolved by sunday the latest and i would get a call or sms, to date i am still waiting. i called again a few minutes ago and the issue is pending on the system as the technicians didnt have the number that had to be deleted off the app so i could re register and use it to control whats happening on my contracts, this was given to them as well. what grates my nerves is the fact things were promised on 3 occasions and not once has any of it followed through.i have now been told that they will get hold of me sometime this week, which at this point seing is believing !!! i find this totally unacceptable. if ive taken time out to call in 3 times to follow up on something that i was meant to be contacted about why should i have to wait longer. absolutly disgusted and would like this issue to be resolved asap!!!!!
