Shoppers Drug Mart complaint: Closed early

I requested a perscription refill and was told it would be ready by 6pm. Usally i just wait untill they text me my perscription is ready. No text by 8pm so i drive to the store to pick up. I get there at 8:30 and the parking lot is empty. The doors are locked. There is a typed leter taped by the front doors saying they will be closing at 8pm starting dec 3. Umm this is dec 2. The big blue sign on the front of the store open until 10 is nicely lit. Several other cars drive through the parking lot when i was there looking to get into the closed store. The quality of this store the last year has been terrible. Most of the regular employees are now gone and it seems they are going through employees like crazy. 25% of the time my fax for refill gets lost and my perscription gets delayed. This could also be the doctors office but they blame the pharmacy and the pharmacy blames the doctors office. Who knows?
