Dear sir
I have called several times one assist to cancel the plan. They have activated the plan without my permission from my hdfc credit card and every day one assist executive is calling me and tells me that they will cancel the plan in 48hrs but no action is taken by they. I am feedup with their behaviour.. Plz help me out. They are not cancelling my plan and also not refunding my amount on 9/05/2018 i have asked them to cancel but every day they are making excuses and not cancelling the plan.
