Dont deal with ImaFinance

I joined ImasFinance through my employer which had an agreement with ImasFinance .Ages ago that agreement ended ,but ImasFinance has continued to deduct a membership fee without fail at the same time they are happy to tell me I have no benefits as a member.I have over the years tried a numerous times to have it cancelled without any success.Their offices ,call center agents and emails are all useless.They operate as an unregulated entity.
