Complaining 3 times to Vodacom care line gets you no where

I am laying a complaint here as after following up with Vodacom 3 times I am still awaiting feedback from them.

I was contacted by a telephone operator and offered a 3G mobile device. I declined this offer as I already have a mobile 3G device with Vodacom. I was then told that this package was cheaper and I would be saving money. I said I do not want to have 2x 3 devices and was told that the other account would be canceled.

I then found out that I was being charged for 2x 3G devices.

I logged this with Vodacom and was told that it would take 14 days to resolve the matter. In my option 14 days is too long to wait, but can I accepted it. I then didn't hear anything and decided to escalate the call. I then received a message it would be escalated but then a few days later received a message to say that the matter was resolved and now closed.

I then decided to use the chat on the Vodacom website to log another call and was told in I would hear something in 48 hours. I didn't get a call back.

So after 3 attempts to rectify this with Vodacom I still don't know what the problem is and why no one even bothers to come back to me on this matter. I find it appalling customer service and it makes me want to cancel my contract with them as a result of being with them for 12 years.
