edgars rcs airtime ****mers

i tried to buy airtime on 16 november using my cellphone.250 was charged to my edgars account balance,however i never received the airtime on the number i requested.since then i have phoned blue label telecoms and edgars helpline multiple times aswell as sending numerous emails but i have received no help whatsoever.edgars and blue label telecom are simply ignoring me.blue label telecom gave me a reference number the first time i called them only to be told later that the reference number does not exist on their system.one agent requested my id number because they couldnt find the reference number they gave me.a week later another agemt requests my id number because they cant find the reference number on their system that they issued.its time to cancel rcs storecard and credit card
