Bureau de poste Shoppers Drug Mart

I had to return a parcel and left a part unsealed as I wasn,t sure which paper had to go inside for returns that I printed off so I waited to seal it when i went in to send it back which they normally don’t have a problem sealing from there I received attitude right from the start and was told the post office has no tape to seal it for me and I would have to buy some in the store off there wall . Poor customer service unfriendly attitude right from the start .
