Bad service

The service at Mondo is horrible never take up anything with then......from their lies when selling products to giving one a headache when they want to cancel their lies.......it's been a month now that I received a message informing me that the contract will be canceled and the sim card stopped working on the 2nd of Sep but I'm struggling to get a cancelation letter because the contract is not canceled ........the company itself enables such bad service the nerve that Sanele has to tell me he's not the one who provided me with the information that the contract has been canceled when I asked him where does that information come from if its still not canceled.
