Telkom's failure to pay me back

In January this year I canceled my telkom adsl line which I had, had for just short of 2 years - paying on time every month without giving them any problems, when I canceled in January I received my final statement showing what I owed Telkom - I went into a store near me and spoke to one thier staff as I was owed money from Telkom, so I asked the staff member if I could just pay whatever else was owing after they have taken what they owe me off, I was told to pay the statement ment in full and then telkom will give me my money back at the end of the month - we are now mid April and I have still not received a cent from Telkom I have been into thier store 4 times and staff have sent requests for me to be contacted multiple times - I am tired of trying with telkom and I would like for my money to be given back right away - let's see if telkom contacts me now?
