one of my IP had a leaking shower and my PM asked me to see if i can organise a shower sealer to seal the damage. Called around a few places and told them to call and liase with my pm. From what i know none of the guys actually visited the property.and gave the quotes based on situation they heard from the PM. Although it seemed one of them (national company) asked for the tennants number in the case of viewing the shower. Anyway quotes came through and i was happy with a local shower sealers quote and was in process of having my pm choose them when the pm said she contacted the tennant to organise a time and she said the job was done. After her liasing she found out it was the one that had the tennants number (national company). Invoice has not been paid and I have no intention to pay them - the quotes 25% dearer and either way i dont feel its right that the business gets a cent from me when i did not authorise them to do any work. Will be contacting my PM tomorrow (she already emailed me saying she will not pay them unless i instruct them too) What options do i have if they threaten me with legal action? Could i threaten them with legal action considering they have tampered with my house without any authorisation? I will ask them for all evidence showing that the job was authorised.
