Pick a Pay Delivery no care taken when fulling customer orders

On Monday I ordered a couple of items just to find 9 items missing. After about 5 follow ups I decided to ask for a refund, which I received promptly. Still unhappy that no care is taken when filling a customers orders. I then decided to attempt a second time. This time all my items are there but some of my items i.e. sugar free drinks was filled with full sugar drinks. Now once again I have to run around and make calls to get the issue resolved. Decided not worth it to use Pick a pay deliver i.e. bottles.
