MONDO 40 GB Data deal MISINFORMATION

I was offered an MTN 40GB sim only deal. I was told if i am not happy I can cancel contract in 10 working days. After receiving the sim card on August 31, late afternoon, it took 3 -4days before I could get it activated. Once activated I tried to access my data usage but it was impossible . I loaded the MTN app but it said my number is not valid. I wrote several emails requesting written confirmation of my contract and amount of DATA. I called a MTN store in Noordhoek and they said they cannot help me, I need to deal with MONDO, I wrote further emails to MONDO and got no answer. I went to a MTN store in Oudtshoorn after receiving a sms saying my night time data will expire. (this was after a few days after activation and limited use). Finally MTN in Oudtshoorn helped me get the cell number of my simcard. MTN OUDTSHOORN told me I have a 10GB contract and Mondo need to answer my questions because they have nothing on their system. Today 11 September, 11 days after receiving the DATA sim card I receive a MTN agreement/contract from Mondo for 10 GB. Fortunately I made a recording of the agent talking to me about the deal. She stated 40 GB DATA and I can cancel and I have 10 working days , if I am not happy. So on day 8 MTN tells me it is a 10 GB deal. This is not acceptable and I wish to cancel/terminate/end this contract. I was not fully informed,my questions were not answered, only after sim activation did I discover that I do not have 40GB data for the month and that after 3 days some data seem to expire. This sounds to me like misinformation.

On Day 10, not 10 working days, I finally got the correct number to call Mondo and cancel my contract. The agent told me that I am too late to cancel the contract, that Mondo cannot help me and that MTN should cancel my contract. I went back to MTN, they told me that they cannot cancel my contract and that Mondo has to do this.

Please can Hello Peter help me as I cannot get the contract cancelled
