PostNet Meadowdale couldn't care less if waybill details are correct. Not their Responsibility.

I'm very upset about the treatment I received at PostNet, Meadowdale. I sell online I've always been very happy with PostNet delivery service. Meadowdale has never been a friendly branch, but it's convenient. They have a fairly new young lady that spelling mistakes on especially clients names, once on my name. I send a copy to my clients and this is embarrassing. Yesterday I asked nicely to please double check. They told me it's not their responsibility to check if details are correct. Then I told the owner a man that I won't like to but I will be forced to use another PostNet in the future. He then lost his temper, very rude man, said he couldn't care less if info is captured correctly, said I must check. They don't hand my paper with details back. I'm over 65 and can't read on my cell if I don't have my specs with me. He then asked asked the lady if I have a parcel and told her to give it back to me to take to another PostNet. This is not professional. Then he refused to give my paper with shipping details back at first. I then left and handed it in at a very friendly PostNet. Is this your policy to treat client and couldn't care less if waybill details are correct.
