Dont buy online pick and pay.

I bought food from mr delivery. The brought the bag but only half the order was in it. I went back on the website and saw atricle was in stock. Aftet i called mr delivery and was told they will take it up with the store. The article was made sold out. Tje calk center told me they sorry but its mr delivery fault, they dont pack the orders, so tell me a new story. Im livid cause of the extreme prro servive, lack of knowlage by the staff and just dont give a darn attitude by pick and pay
