debited twice for one vehicle warranty plan

I called innovation group to upgrade my warranty plan on 08 Jan 2015 and I was promised that the old one will be cancelled in 30 days and they will activate the new one. since then the new policy and the old policy are debited on my account . I called their customer services and spoke to Lebo Ndawane and he said that he will log a cancellation and be treated as new . my question is what about my money from February.
