rcms and edgars together dont want to cancel contr

I subcribed to edgars airtime contract for only six month.it started in july of 2014 it suppose to end in december of 2014.went to edgars in november irequested them to cancell this contract. Iwas told that it will end in november of 2014. In january ireceived airtime again iwas amazed because ididnot expect it since i asked for cancellation. Iwent back to edgars they gave me aphone to call rmcs .italk to rmcs they promise me that it will be cancelled they then gave me the refernce number after telling me they wana ask some question before the cancellation is made to my account i am real disgusted the way edgars and rcms are u doing this.idont want this airtime contract any more please chancel it with the immediately effect.dont force customers to be ur customers.our rights as customers are infringed why are u doing.may be ihave to take this to higher authority.they might solve it other wise.please dont call me.because an busy during the day just cancel it
