Condescending manner

It was on November when I requested for the immediate cancellation of my policy with them and took another policy from another company, but momentum never stops deducting money from my account up until January and I wrote to them before the end of January and they said they will refund me half of what they debited and they said half must be paid by the new company that I joined no reason to that and update no refund has been paid to me this is condescending and taking me for granted.
