WHAT IS THE MATTER WITH THIS BANK??????

My matter that started 6 weeks ago is still not finalised in spite of all the hours and hours spent trying to get a simple matter out of the way. AND NOW They were unable to sort out my sim card, so I cancelled and went to a different carrier. CAN YOU BELIEVE??? this has been going on for a week and they still have not cancelled my contract as they said they would. My new carrier is unable to switch my number over and I am still having trouble with my FNB sim.
