UC overpayment info vanished!!!

Hi all

Was told back in May that we owe 3.5k as were overpaid as we didn't realise about the capital limits. We had to upload lots of bank statements from the start of our claim. My wife spoke to a decision maker and she informed us of the figure owed and said we would receive a letter off debt management.

Since then I must've rang universal credit and debt management around 10 times. We have the money put to one side ready to pay it back.

All but one time UC, over the phone, have said they can't see an overpayment. The one time someone managed to find the figure calculated back in May and told me to ring debt management saying the date the figure was calculated and the amount we owe.

I did this. Someone from debt management said they could also see the figure and that they would ring me back once they find out why we haven't received a letter or asked to pay it back yet.

They never did ring me back. Me and my wife have rang back since and they are again saying they can't see anything about us owing money!!!!

It's driving me crazy and I am now questioning whether it could be with the fraud team. I have to keep rationalising it - we notified them once we found out about the capital limit. The decision maker seemed fine with all the bank statements and answers my wife gave to a couple of questions.

It's just really frustrating. Anyone had anything like this happen? Any ideas of how I could get this sorted
