Miscommunication/not understaning their own Job

My fiance had recently taken out a contract on the 02 May 2015. We were then told that we would then only pay the end of June being the 30th. This was reiterated as we couldnt believe it... anyway end of May comes and zap debit order autopage we were not aware of this as we were told to only pay end of June. SO I call and no one ever returns my calls, must be a ghost on the other end of the line that I leave messages with. WE drive to cape gate mall to have this sorted, I must have a car that does not run on petrol probably water. SO ALL MY EFFORTS IN TRYING TO SORT THIS OUT IS ME DRIVING TO YOU? WHEREAS I AM THE CUSTOMER YOU CLEARLY DO NOT LIVE UP TO YOUR STANDARDS AS THE CUSTOMER COMES FIRST AS LONG AS YOU GET YOUR MONEY THEN YOU DONT BOTHER. PLEASE DO NOT SEND MY SINCERE APOLOGIES RATHER EXPLAIN TO ME WHAT WILL BE DONE COS THIS IS NOT THE FIRST i refuse to drive to cape gate for the 10th time I dont own a gas station to drive uneccessary petrol out for incompetence! I will complain everywhere I can so that I dont hear \your service has been suspended krap"all the time"""
