Yesterday I emailed them to make an appointment, as my molds need to be remade really really badly and I finally have a little bit of headspace to spare to think about such things.
Today I get this email: "Could you call me at ###-####? I tried the number on your account and there was no answer."
I sent back the polite but pointed response: "I cannot use the telephone due to my hearing impairment, hence my attempt to set an appointment up via email."
No response as yet.
