I couldn't see an email address listed so it looks like all communications are done via a webform/web address.
I live in Surrey so can't really help much on that front as it's a two hour drive from here. There may be some other people on this forum that might live closer or perhaps have spoken to people at Spax in the past.
I hope you get your problem sorted out
