MTNZF notice was not posted though I sent both my postal and my residential addresses. Please be of help to me in that regard.

Please visit the website below for calibration or support.https://www.breathalyzers.com/index.php/alcohawk/alcohawk-calibration Looks like you have to send your unit away to have it calibrated. I would send them an e-mail enquiring about cost details before posting the unit to them. And double checking the postal address where the unit needs to be sent.

Contact Canada Post with the address or look for it on the Canada Posy website.

Hope this helps.

Did you send the postal order registered post, where a signature is required on receipt?

You basically have no proof of posting it otherwise, it could be lost in the post.

If you sent it recorded delivery and it was signed for, then you could get the police involved.

I would open a case with ebay in case they have had complaints from buyers with this seller before. If you get the police involved, give ebay the incident number as it helps them with their enquiries.
