Worst customer service in the country!

After having some billing issues with my contract, I had to make two trips to Vodacom stores, one in Mall@Reds, the other to Menlyn. After the Menlyn store consultant ensured me my issues were sorted out I thought all was well, untill I checked my balances on the Vodacom app. After two calls to the call centre on two different days, with two seperate reference numbers I was told each time to wait 24-48 hours for a call from the "back office". It is now more than a week after my first call and still no one has even bothered to call me back. All the while the call centre consultant is unable to explain to me how my current bill jumped from R1660 to R2509 overnight. I have been a loyal customer for over 13 years, I have never missed a payment, yet I received no assistance that was in any way helpfull. After this whole billing disaster I cannot wait to cancel this contract and take my business elsewhere.
