Most likely Mathew is on holiday somewhere, it is that time of the year, I bought some items from him about 2 monthe ago and there was no inkling of anything untoward occuring and the website is still up and running and was last updated a few weeks before Xmas.
Have bought from Mathew several times over the past 8 years or so and have never had any problems, can recommend him for good service.
just spoke to him now regarding a pod . He was in holidays. Better give him a call if you want to get in touch because i think he has a few emails to reply.
