Consultant down graded my contract and **** about it

I have been querying this concern for the past month now. On 16 May a consultant called me regarding my data contract upgrade he advised that he can offer me the same package of 2 gigs data one being day and 1 being night with a Vodafone 7” tab for the amount of R69 I agreed on this and the upgrade was done telephonically. This month my data was used up when I checked my invoice I see that I had been dropped to a 1G top up

I called in on the 13 June spoke to Shirley Ref 1- ********** ********** she said they will review the call that was recorded and provide feedback, I did not receive any feedback

I called again on 22 June spoke to Excellent ref ********** 52 said he will feedback and I received nothing, he then told me the call was resolved but no comments to say I am being reimbursed and I am still refelecting on the 1G top up

I called again on 27 June spoke to Thando and then again to Zinzele who said they will feedback and advised that Vodacom could not retrieve the records … what bullsh#t is this???? why are calls recorded if you guys cannot retrieve it

This matter needs to be resolved asap this is costing me money and I am going to take action against Vodacom
