Anyone in Prince Rupert had their mail stolen - mail that they were expecting to receive - or mail that they sent out that never arrived at the intended destination/address?

This past summer I sent several envelopes/mail to different Prince Rupert destinations/addresses - some sent via registered mail and some sent via regular mail - all included Visa prepaid gift cards - while none of the intended recipients received the mail (including the registered/tracked mail) all gift cards were used at the Prince Rupert 7-Eleven (Visa provided location, dates, times of use) - obviously the mail arrived to Prince Rupert and was intercepted.

Is something going on at Prince Rupert Canada Post and Prince Rupert 7-Eleven?
