PC Cleaner Paid for 1 yr and after 6 months said it expired Vancouver BC Canada

Software quit working so I contacted support.  Was told my subscription was expired; I send copy of my receipt date 12/24/12  that showed renewal date of 12/24/13.  They kept coming back saying it was expired and I had to pay the yearly fee again to reactivate.  Even after numerous attempts, they refused to honor my paid subscription.  I have been a customer for 2 or 3 years and have always renewed on the date of subscription expiration; still, they refuse to work with me and honor my subscription even after they received proof of payment.  I guess they feel they can do this as they are located in British Columbia Canada; I will find a company here in the US that honors their agreement and has great customer service.
