Unacceptable charges and timelines to rectify

On the 31st of August a logged a dispute against obscene data charges to my already premium VIP premium package. The charges me 3 times the amount I normally pay for usage to data on my phone. Service Request Ref No. 1- ********** ********** . Vodacom then after deducting the amount from my account (close to R7000) says it takes 3 weeks to investigate today after the 1st service provider said it would take 72 hours! How unacceptable and the behavior in resolving these matters are ridiculous. It's one of the reasons I have not updated my contract with them. Vodacom and their fees a ludicrous and aren't comparable to anywhere else in the world (including Vodafone in Australia!) I am absolutely disgusted and will be taking my business elsewhere!!
