Bad Service and *****

I would to express my disappoint with Jet. I have a jet account which I paid off last month on the 24th. I immediately send an email that the account be closed. It took them sixteen days to get back to me and when they did I had an unknown balance of R560 according to their email. I rep**** asking about the balance I took them six days to reply and I got a statement which has a purchase amount with a date. I asked that the card be blocked in January since I lost it when my house was broken into and I don't and to my surprise its still active. Had they blocked the card and closed the account when I requested this would have not happened. I also see cellphone insurance I don't know of on the statement. Had they rep**** on my emailed quicker this would have not happened. My account number is . Contact number ***.
