Furniture Never Repaired Or Delivered Back

We contacted Decofurn Kenilworth in September last year to assist with repairing some Decofurn furniture that was out of warranty. We were then referred by Julian to Matthew at Sapphire Fire Retardants as their main repairer. Matthew then came to collect the furniture and we paid a 50% deposit. We then got 2 items of the 6 that we gave to him back in December and Matthew then disappeared and stopped taking our calls. We again engaged with Decofurn Kenilworth to assist with getting in touch with Matthew and have subsequently been told that, just because they referred him to us does not mean they are liable as it was not booked in through Decofurn. Matthew has still not returned our calls, or given us a date as to when the work will be completed, all the while having been paid a deposit for work, and having our furniture with him. Shocking service delivery from both Decofurn Kenilworth and Sapphire Flame Retardants
