- CMCarmela MarinoSep 15, 20261.0This is not a main post office. Do not waste your time
- TWTom WildeSep 1, 20265.0Woman behind desk in travel and money extremely helpful. Had a problem with my special deliveries and she sorted no problem.
- HDHelene DerijckeAug 2, 20261.0I am very disappointed that the package I sent from here on July 15th never arrived in the United States.
- DGDick GrantJul 17, 20265.0Great help in the center of the city
- TBTess BeeNov 29, 20221.0Incredibly ignorant and rude staff who claimed no knowledge of a fairly standard postal service. Thankfully the main Post Office on Queen Street knew what they were doing. Not only would I never use this place for postal services again, now I have experienced the rudeness of the staff, I will never use the convenience store again, either. Don't waste your time - go straight to the main branch. If I could award zero stars, I would.
