Best way to contact Ortovox (Canada)?

Can anyone suggest how I should go about contacting Ortovox to get my transceiver repaired? I have phoned multiple times on different days, left one voice mail, and several e-mails. No answer yet... 1-2 weeks later. If anyone is curious one of the battery contacts on my M2 has broken off from the circuit board = no power.

I have not tried the international contact info, nor the USA. (I would prefer to not have to ship out of the country)
The contact information given on the Ortovox Canada website is

ORTOVOX CANADA LTD
4610 Bowness Road NW
