Decieving customers

Guys if you receive an sms offering you a free airtime on vodacom, don't respond that sms you might be entering into a contract that you don't even know you have one, my vodacom sim is now managed by rmcs, this people are deceiving customers, they have blocked my simcard now, they work with Edgar's too, cancel that contract, you offered a free airtime because I was buying a lot of airtime at that time, cancel that ********** contract and unblock my *** number
