If you owe them money you receive your reward pretty sharpish minus the amount to be paid back.. This has been the case for 5 of My friends.
I HD a letter saying if my estimates were correct ( it was meant to be actual figures but they stuffed up so had to call again) said once renewal done and them. Figures correct they will Owe us over 3k..I confirmed the correct figures.. 4 weeks later still nothing. It's so infuriating as would be ideal. Towards a private rental deposit but it's taking forever.
That's my theory.. I'm. Probably being grumpy.
