Estate agent not giving bk deposit, won't give us landlords details, help!

We just moved out of a house in England and moved back to Ireland after two years there. Now it's been nearly 3 weeks since our tenancy ended and the estate agent has a check out report which is done by a separate company. This company has listed the most petty tiny little things, and the estate agents has come up with costs themselves, here is the list they are proposing to keep over half of our deposit:

Checkout fee £115.20
Red pen marks and scratches to heating units and controls £20.00-compensation
Further cleaning required £120.00-compensation
Dents to fridge door £15.00-compensation
Stains and marking to top of stair left hand side £15.00-compensation
Bannister has pen marks £10.00-compensation
Several marks to all walls in bedroom two £40.00-compensation
Several blue pen marks all over bathroom door £10.00-compensation
Pen marks all over back of bedroom one door £15.00-compensation
Stains all along top of wall by window and Several marks to all walls in bedroom one £25.00-compensation
Several marks to wardrobe door in bedroom one £10.00-compensation

Please know also that new tenants took the place two days after we left. There were cream carpets all upstairs which I professionally cleaned, we have two young kids, the stains they state was mold which I tried to remove plenty of times while we were there. There is no explanation of the further cleaning required. We spent at 1000 travelling back and forth from Ireland to clear out the house and clean it. We feel this is all wear and tear and just a way to steal our deposit.
Also when we first rented the house it from a different estate agent who don't charge a check out fee. This new estate agent are trying to charge 115 check out fees!! Mind blowing.

The estate will not give us the landlords details so we can appeal to her directly.
