not complying to the turn-arount time

i received calls from late last year for the airtime contract from edgars that they will sell me airtime of R25 and i will get R49 on my account. i kept on declining this application as i was not interested on it. i then recieved airtime on late february of R49 and when i call Vodacom(my net-work) they confirmed its from RCM which works hhand in hand with edgars as they deduct the money from my edgars account. i then called the call center on thursday last week and i was given a refference number *** by Owen(call center agent) and was given 48 hours for the cancellation. even now they havent cancelled and no one has called me or said anything. i wasted about R50 of airtime trying to sort this matter up on last week and about R30 today. still i cant get through because their line is for-ever busy. i am a regular customer and i dont like complaining or feeling this way with edcon because i recoment you guys alot. please cancell the contract and re-embuse me with the airtime i had to waste for nothing. and i will be happy to get that fixed soon because the functions on my phone are now limited due to that contract.
