financial difficulties thanx to vodacom

I take full responsibility for not making my payments so I called to ask if my debt date can be moved to the 25th of every month a few weeks later I called to check if its been set for the 25th and no it was set for the 21st.I then spoke to a gentleman called Dexter who was at the time helpful as he said the call would have to be listened to then he will call me which he did and told me that I will get a ref number on my alternative number and the back office will call me in 3working days which they didn't I again called yesterday morning and spoke to an advisor who said I should not go make a payment as they will debt which they didn't and I was suppose to get a call back from her this morning for an update which ofcoz she hasn't called now I am suppose to pay a penalty all becoz of one person who put down the wrong date and no follow ups being done.can't wait for my contract to end
