Trying to cancel a contact

RMCS got my husbands cell number from Edgar's and took it upon themselves to give him promotional airtime monthly, which has now changed him from prepaid to contact at Vodacom. We are trying from 25th January to have this cancelled. It is costing me unnecessary money, and all I keep getting is more reference numbers and being told to wait 48 hrs. Yesterday, after insisting to speak to a manager, I spoke to a person by the name of PAULINE. She again wanted to give me the same story. I asked her for their physical address so I could go in personally. Her reply to me was "you must Google Blue Label Connect if you want it" All we want is this contract cancelled immediatly and they should send their staff for customer care training.
