No data allocation as per contract taken through MTN

Here I go again..... I extended one of my contracts and opted to take a data package/sim only option for 40g daytime and 80g night data in April 2020 which was advertised at R299.00 per month. From the start I have had issues with this package as the info placed on my invoice and the data allocated to the package is not what it needs to be. I have now asked MTN to send me proof of the allocations made since April 2020 and proof on what data has been used since then. I have reason to believe that MTN has been ripping me off with the price I am paying and the data placed on my contract. I have asked them for assistance since 28 April 2020 and have had no positive feedback on what is happening to this issue. I have logged numerous complaints and have received a few references, but up to date no feedback or a positive answer in this regard. Please help - I have all the relevant info on email. I feel I am paying for less than what I have signed up for and that MTN is ripping me off. Until such time that they can prove to me that they have allocated the allotted data and that I have used same, I will believe that MTN is *****ing my money on a monthly basis. They are quick to block your number when you don't pay, but when they have to give you feedback, they can take all the time in the world. I am at the point of taking the matter to the consumer council and the telecoms ombud.
