Awful, Horrible experience with Martin& Co ; STAY AWAY!!!

Martin &co tried to charge us a ridiculous amount (TOTAL £2,128.80) and our deposit for the general wear and tear, they also tried to charge us redecoration costs.(We maintained the house well, cleaned everything properly w/o any breakage, handed over to them as it was received.; #We maintained the house as Smoke free (As we both don’t smoke/drink), Pet free , there are few acceptable wear and tear which are due to one-year usage /tenancy)When we refused to pay(We submitted all the required proof as requested by them ), they started negotiating(We initially agreed for £75 where they made us agree for £120 with an immediate effect as if they are going to release our deposit, saying they are doing us a favour by charging less which we again said no to. When I asked to see any proof of the costs (an invoice) they stopped replying to my emails altogether, leaving us to have to wait for our deposit.
