Unhappy customer

Vodacom customer service is really delayed I called them on the 24th June to renew my 299 contract that I had for 2 years it was 500gigs data 10mbps line it was a black friday special. I asked the consultant if I can keep my same package and continue as I really had no problems for the duration of the contract the consultant said that I would be getting exactly what I had and my contract will continue if I do want to change my mind I have 3 months to do so to renew another package. I agreed and that was done. 30th July was unable to connect to my wifi lte router because my data ran out upon phoning customer service I found out I have only 200gigs and not 500gigs as my original package. I was told that that upgrades consultant renewed me for a package that was not my original package. I did not agree to 200gigs. I wanted my old package. There has been no correspondence since that day I was told an investigation will be done this is my reference number: 5-cs22DQ7v7. I'm truly disappointed in vodacom. As a client I was told that I would get exactly my old package and therefore paying 299 every month. This is absolutely unprofessional I also work in a retail industry and i make sure the client gets what they need and I'm always transparent. But this was really bad. Vodacom I'm a loyal customer this is difinatley not on!
