I'm gatvol with their shaddy dealings

Such an aweful service, at the end of my contract they did not even bother to call rather they kept me on a normal rating of which was double the rate that I was on...after telling them to cancel they tell me that I have to give 2 months notice for a contract that has already expired. This is a daylight ******* and I'm so ****ed, every explanation was so shaddy. Never again!!!
