Rain is a ****,ive been billed twice for a service that was not active

Rain debited my account twice this morning, i am trying to call them to find out why and their line is not going through, it is very disheartening for me to trust a company with my banking details and they do as they wish and when you try to get hold of them to find solutions, they are not available, i am being charged for something that i did not use the service because it was not active, Terry from Rain is saying that on their system it shows that the service was active even though it was not on my side, how am i going to survive this month with R1000.00 being debited from my account and rain being horrible and not willing to assist
