HARRASSMENT OVER CLOSED ACCOUNT

THIS ALL STARTED LAST YEAR WHEN I CLOSED THE ACCOUNT AT KEYWEST MALL IN 2014, I was not told that there was to be a separate cancellation form for the cellphone contract, which I obliged and paid in Dec or Nov 2014, a few months after I had filled in the forms I was contacted again by TFG (The Foschini Group) and told once again that no payment had been made due to the non cancellation of the of the cellphone insurance, which I then assumed that *********** people did not submit to their respective departments, I then went in end of March Beginning April and Settled again being told that they would Process it and send it through, I had requested a copy of the form and they had refused at 1st, I did however get a copy eventually, I am now once again being harassed for Stupid ****ing idiots who do not do their job, I am highly frustrated and I am not getting any assistance, they have today ( 19-Aug-15) sent me a mail threatening to take me to court for their staffs Incompetence, I am unpleased and I am seriously tired of these people, it is my Hard Earned money that I have paid to them on more than one Occasion for their Negligence.
