Incorrectly debited account - delay in refund

I spoke to a consultant on 25 June 2024 and repeatedly told him that the inception date of the policy should be 1 August 2024 as my existing policy was still in effect and the premium for that policy was already debited from my bank account for the ensuing month. When checking the policy document on 26 June, it stated that 1st for Women would be debiting my account on 26 June 2024. When I phoned them to point out the error, I was told that that the debit order was already scheduled and they were not able to cancel it. I just had to accept that they would deduct the premium from my account and then go about refunding me. I did everything they asked of me and yet I'm still waiting for my refund. The cherry on top is that they spam called me multiple times trying to upsell the policy. Read the room. I wanted to give you the benefit of the doubt but unfortunately my experience has been too unpleasant. It's been two since your mistake and it is now prejudicing me financially. You were quick to debit my bank account incorrectly but are now twiddling your thumbs when you have to refund me. Trying to get this resolved with FFW representatives have proved fruitless and unfortunately this seems the only way in which my complaint will receive the necessary attention.
