FNB Connect Agent fradualently misrepresented their package and no rectification done by FNB

January a FNB agent called me to offer me a sim card and data package.on the call the agent made mention that for a value of R139 a month i will be receiving 1G free plus 600MB,100 minutes and 100 Sms.before accepting this month to month package i confirmed with the guy the amount of data that i will receive and he confiremed the above.On over conversation he confirmed i will need to pay R80 sim card delivery fee,an amount apportined for the package since it was already mid month.i concluded this agreement with the knowledge that i was to receive the above data as presented to me. Come month end an amount not agreeing to the one we concluded the deal based on was debited and above that the data was only 600MB.I called FNB to enquire and i was told a diferent story that im to receive 600MB and the initial amount to be debited on the first month was not the one we had concluded the deal based on.I told the person who was assisting what i was sold and im expecting to receive that.i was told that an investigation will be done and the recording that i requested i can listen at the bank.which i was fine with that.days later an agent called me to say our forensics has listen to the conversation and they said I agrred to receiving 600 MB for the 139 which was not the case I agreed to 1G free monthly pluss the 600a.I then posed a question to that person to say did you yourself listen to the recording before you can atter such statement? the person said no.to cut story short i Requested that he listen to the recording, FNB then got back to be to say i was right the agent mention that i will get the 1G plus the other benefits on a monthly basis.I was then offered that i can cancel the agreement and get full refund or i continue with the package.I then requested that i work on the calculation and see if its financially viable then i will get back to them.days after doing my cals, l called them and explained my last conversation with the bank ,I was again told same story that I agreed to the initial agreement ,everytime I call their response then i would requst that they listen to the recording thats when they agree that im correct.I then requested the deal to be cancelled with immediate effect and requested my full refund thats when they started pushing me from pillar to post when i called.the last agent even dropedv my calls a couple of times.On the 15th of March i requseted that this be terminated and i was told they cant instand i was billed,the last time i called they said ther termination occures after 30 days.
