Poor customer service. Refuses to Pay refund.

Disappointed at their poor service. I canceled 2 policies with them in May. My policies were stop orders. They have been debiting my payslip. So I emailed them asking about a refund since they have debited me for may ,June and July. One of their consultants called me and told me she will send me a refund form. Then she sent me an email without a refund form. I emailed back telling them there's no attached refund form. They emailed and told me I won't be assisted because I didn't suit ID and bank statement . I sent those documents. But still they did not send me any refund form. Up until now they have not refunded me the premiums they kept debiting even after cancelation. At this point I don't even believe they will stop debiting at all. It's like their angry I canceled the policies. I'm angry because I still have 3 policies left with them of huge premiums amounting more than 1k. If this is how they treat me for a mere refund. What will happen the day I have to claim from them. I am even considering canceling everything with them at this point.
