I'm still struggling to get my account canceled!!!

I have tried to cancel my studies with Intec since February 2015. I had to quit my job in order to take care of my sick mother so I could not afford it any more. At first I asked them if I can put my account on hold, they said no. I then asked for the cancellation form to cancel. I only received that form in October 2015, even when I have asked for it several times. I could only afford to send back the form in November 2015. I still received Statements to my account, I sent an email to ask why I'm still receiving statements if I have canceled. In the beginning of January 2016 a lady phoned and said that she would start to process my cancellation request at the one whom was supposed to do it was on leave. I would get feed back within a week. I have waited and I heard or received nothing. Again I received a statement for January 2016. Again I rep**** to the mail to ask what is going on.... Last week, Tuesday I received a phone call to confirm that everything has been processed and that I would get an email to tell me if I have any cancellation fees and if my monies would be refunded back to me. She said it would be between 48 and 72 hours. I still received nothing!!!!!!
