Hi and welcome to SAYNOTO0870.COM.
Website is
www.midasprint.comCalling either 01495 244 363 or 0800 612 7621 answers with a recorded message redirecting to the 0845 number. This is voiced by the same male as the 0845 number.
The 0845 544 prefix is allocated to "INET Telecoms Ltd (Voipfone)", change date 08/2008. This suggests that it may be a VoIP system (that is it connects via the internet) provided by
Voipfone.
This may either not have an alternative number are it could be one of thousands and thousands anywhere across the UK allocated to Voipfone.
In summary, I think that there's no alternative to be found, or at least, if there is, then it's a needle in a very large haystack.
