Well I gave them a chance to respond and telivo.com have, thus far, ignored my last 2 attempts to contact them through their 'contact' page on their website.
They certainly don't make it easy.
Can you imagine what potential buyers would think if this was the kind of customer service responsiveness that you gave your customers?
So, if you run a business, here's my advice for the beginning of good customer service:
Make it easy for people to contact you!
So, as a compromise, I've written (for the third time) on their contact page asking if they would accept an emailed PDF file instead of a letter or fax.
I'm far from impressed, I'm not a satisfied customer and I'm not optimistic about getting a response.
