I contacted Sleek Storage via the online form. Aidan got back to me to ask what I wanted (understair storage) and sent some sample photos, which looked ideal.

Unfortunately I paid this man a deposit of £180 and he gave me a date due to a "job that's been cancelled". He duly emailed tod say he couldn't make it as his van had been broken into and rearranged for a Saturday ("we don't usually work Saturdays but as it was such short notice to cancel we'll come out for you"), but didn't show up.

Perhaps unsurprisingly, his phone then went straight to answer phone repeatedly.

I then checked Trust Pilot to read all of these similar experiences.

Luckily I was able to retrieve my money via the banking fraud team and will report to the other relevant authorities.

Possibly obvious thing to say... but best avoided.
