Unauthorised deductions from deposit

Has spoken to Chris the manager re Unauthorised deduction of monies for paint from deposit. When students took occupation of flat 2yrs ago it was not painted. We washed the bedroom walls & replaced 2 down lights.When we moved out 22December we removed the 2downlights we had replaced.Their was/is no need for painting, if needed it would be for wear & tear. My daughters had stuck 3 A4 size posters on Wall. This is easily removed and leave no marks. The person by the name of Lawrence who inspected property with my daughters at handover said they must not worry to remove posters as they were in anyway going to paint that room.On that basis my daughters signed the handover inspection form. When my refund of deposit was made to my account I noticed there was a deduction which was for painting & replace 2downlights. I have left 2messages for Chris to contact me, but to no avail. I have also send emails to Yolanda Stenberg & Ivone Serrano. My daughters were misled in signing the inspection form & I need my money back immediately.
