Poor service

The service I received from Vodacom is shocking. I first logged a query on 14/01/2019 at 10:18 regarding unauthorised premium increase from R388 to R449. The discount of about R52,63 that I had on the contract fell off at the end of the first year of the contract. To this day no one can provide an explanation in this regard. The contract has since completely expired. I logged several queries and each time I would be told the query is closed and a new query would be logged, The following are all the reference numbers I received and none of them were resolved however closed, *** *** *** *** *** *** *** *** I spoke to Palesa, Smangele Ndhlovu, Allan, Ayanda, Ntombi, Dijeng, Thokozani, Mpho, Sinazo, Jabulile, Dumisani, Simphiwe and shockingly, none of them could resolve this matter, I kept being put from one person to the other, team leaders and senior technicians. There was a note that the call recording needed to be retrieved to verify the contents of the contract, I am still waiting.
