Dishonest company - Beware!

I used the services of this company in December 2019, and mistakenly paid the company twice - I had set up an automated payment before travelling, which I forgot about, and then made a second payment on my return. I immediately phoned the owner, Henco, to inform him of this (and sent him details of the payments), and he assured me that the duplicate payment would be refunded. This has not happened, and after many calls and e-mails (over the course of 3 months now), my money has still not been refunded. Before this, Henco always answered the phone (there is no land line, just 3 mobile phone numbers which he answers) and very time I try to phone now, he cancels the call. He has also not responded to my e-mails. I will never deal with this dishonest company again, and I'm writing this post to caution anyone who plans on using the services of this company.
