PAXI and pep has the worst service in my opinion

I'm appalled by the service of PAXI and pep, you get a date for delivery but no one gls you anything and when you call they only say sorry like sorry is going to fix having my son leave without getting his school stuff making me look *********** whilst I did not get anything done wrong. It's frustrating cz now I'm being blamed for their mistake and it's business as usual for them. I'll rather have to use postnet nest time the service for PAXI is awful very awful.
