Vodacom service unsatisfactory

In June 2018 I contacted vodacom to enquire about migrating to a sim only package. I was then placed on a package that offered approximately 500min and 5GB per month. I was assured that the package was similar to the red Contract I was on. I called again enquiring about the minutes i receive per month and was informed that I was put on the wrong package. I was given the Smart top up M+ which gives 400min and 400MB. When I requested that they listen to the call I made in June , they said that it would take 7 working days to resolve. I also stated that if the incorrect contract was given I would like to cancel my contract with Vodacom entirely and with immediate effect. It has been over 3 weeks. I contacted Vodacom again today and was told that nothing has been done to address my query and that feedback will be given in 48hrs.

I find this level of service unacceptable and I would appreciate if my contract is terminated immediately.
