Supersonic - Terrible service and Data Theft

I have been a Supersonic client since November 2020. To get the contract was a breeze, its after you a client that the super service stops. Delayed billing etc.... .A billing query took over 2 months to get a response and still nothing. Upon me asking to cancel this contract i was told that an agent would contact me to cancel this contract. No agent call, just an email on the last day of the month stating that the contract will be cancelled. All purchased data R150 worth will be forfeited and there was now a collection fee for the router, all of this was not disclosed when taking the contract. I was forced to ask for this contract to stay open in order to utilize my data and upon activating the contract again my data is no longer there. Plenty of promises too, the line manager promised me there ISPA number and still nothing. Do not take telephone contract with this company, they do not disclose all their fees and T&C's. Be very wary. They seem to find another way to get around the law to lower data charges by finding adhoc fees.
