Right, an update. Firstly, a big thank you to Dave who got hold of this for me and turned my disappointment around. He put in some effort to come to my house, take new impressions & return to me my new earplugs (along with the impressions) well within a week.
Oddly, one of the plugs didn't seem to fit/feel right, but was assured if I sent them back, they would be sorted. I sent them back so they arrived back at Ultimate on Weds last week, saying to Dave that I had hoped to use them this weekend for a planned trip away, so he said he'd do his best.
Anyway, Friday morning I got a phone call from my wife (they were being delivered to her shop) to say they had arrived. I used them this weekend for our trip and, although I'm going to have to get used to the slightly firmer feel in my ears compared to the foam jobbies, they seem to work a treat!
So, an upset customer turned around into a very happy one. I appreciate the extra effort put in by the guys at Ultimate who obviously wanted this sorted for me, and would say thanks to them too.
If this is the customer service Dave expects us to receive from his company, then I would whole heartedly recommend them, as I now feel that my 'issues' before were just an unfortunate set of circumstances that just happened to effect me & my order!
Anyway, as I said above, many thanks guys. It's nice to feel like a valued customer!
