MTN 30gigs not loaded and service is disgusting

I want to make a point here.

Since I have upgrade my account 2017.06.19 and this was done on the telephone. The mess up came when they sent me the wrong phone. Then They cancelled the upgrade and told me i must go to the store to upgrade. So since then i have upgrade at the store and then i was told my account was going to be R229 MYCHOICE Talk +S and nowi am paying 329. Consultant doesnt want to do anything.

Now the promo service which was advertised on the catalog. 30gig x 3month which is valid for 30 days. I spoke to managers and consultants and the last manager said i fortiet it because it was for one day and i told them its supposed to be valid for 30days not 1 day and its not pro-rata and i told the supervisor that how can it be pro-rata 10gigs if i get the full one. I told them its is false advertising and if you actually here the call you will understand what i am saying and the supervisor doesnt want to listen and want to make me the wrong and the customer is not right and they call centre agent is always right. The supervisor said i wont get it back because i used it up and i said how can i use it up because it was supposed to be for 30days and i said that it is false advertising and the supervisor didnt want to understand what i am saying. They cannot see anything on there system that my 10gigs supposed to be loaded and i told them it shows on my unbilled invoice and do want me to send it to you? The supervisor doesnt want to listen. I am sick of trying to sort this out because i am going to take this further if i have to because i dont feel they are doing there jobs and they are they worst customer service provider. i wish i could just cancel the contract and go to some where else. but i cannot because MTN is okay for me but this has to be sorted out ASAP
