Deposit Protection Scheme

I always heard the carpets and walls were tear and wear

Depends on the extent of the wear. It's hardly fair if there are massive stains where oiled has been tracked through or the dirt is ground in because someone has not hovered as an extrem example.

i never pay the last month rent when i am leaving a house

Ed has had a bad experience with this one but the idea behind the deposit protection scheme is to avoid people having to do this.

Did you have proof of postage? Always useful whenever anything legal is done to help with situations like this postal strike business. It's unfortunate but you don't know how much of the disputed amount you would have received back if you had got your evidence in on time.

They should have been more flexible due to the postal strike. That bit is unreasonable.
