Capital Legacy double debits my account and cancelled policy instead of refunding and correcting the debit order

Capital Legacy kept debiting me twice, one debit at the end of the month and the other, at the beginning of the month. I reported this on various occasions with proof. They promised they would investigate, until now they have not investigated. I requested a policy cancellation and they were quick to cancel the policy. What a pathetic customer service. I demanded refunds for those erroneous amounts, they promised they would refund, they still haven't refunded. What's important to these people? That people have "WILLS" or these double debits. Please people, this is very serious.
