Warning to prospective buyers!

i bought a double garage and site doors from Door-zone centurion in September and October 2019 cash. They gave me measurements to guide the builder and promised to come and ensure that the structure is built to specifications before manufacturing and installing the the doors and said to call them as soon as the builder had completed the door structure. I went to their offices as soon this was done only to find a notice note on the door indicating that they were on an indefinite strike and they left no alternative contact numbers. I kept calling and physically driving to their offices and there was still no sign of an end to the strike and the next trip to their offices was met with the shock of my life "offices to let". There were only telephone numbers of letting agents. This was on a Thursday and the following week on Tuesday i went there to try and contact the letting agents and enquire from the surrounding companies about their whereabouts only to find that the same staff, same facilities were operating under a different company name and claimed that Door-zone has been liquidated and advised me to claim my money through my lawyer and provided contact numbers which i am yet to put to the test since my lawyer was unavailable at the time. This must be a warning to prospective buyers!
