Failing to close account

I have been trying to close my FNB account for days now. Went to the branch and they cant close my account because there is a pending transaction of R89.60 to DSTV, which happened 10 days ago. The bank told me the DSTV has not claimed the money So I went to DSTV and they tell me the money is already reflecting in their account and the problem is with my bank. So I go back again to the bank and was with 3 different tellers for OVER 2 HOURS as they were forwarded from one department to another on the phone. It was so bad they ended up being referred to the very first number that they tried to call. Needless to say, after 2 and half hours I left in the very same position I entered the bank! I am planning to leave the country in a few days and will be away for several months and everyone keeps telling me \there is nothing they can do". Surely there must be SOMETHING! I pay lots of money for Premier banking and not once have I felt someone trying to take the initiative to help me and make banking easier for me.If I leave the country without closing this account I am going to be charged more banking fees"
