Failure to refund amount paid in excess

On the 23 of December 2024, I called in to Daly Credit Corporation to settle my account, of which a debit order already deducted from my bank account on the 20th, however due to a delay in their systems the amount was reflecting but not allocated as yet to my account, and the settlement amount excluded the debit order amount paid. So, to speed up the process Nosi the agent who I spoke to ref *** on the 23rd of December advised me to pay the amount and on the 3rd of January they will refund the debit order amount seeing that it wasn't reflecting at the time. to date 14/02/2025 I have not received my refund, and I have probably made 100 calls back and forth to no avail. the matter was referred to a manager but every time I call, they cannot put me through to them and the call center agents keep on promising me a call back, but they never do. they give constant call for you to pay your account but when they owe you, they want you to chase after them. all I want is my money and nothing else. Daly Credit Corporation please pay my money back.
