Baby Register inconvenience and rude assistant manager

I initially had an issue with creating a baby register at the store in Menlyn as they were rude and I was told to write everything down on paper and then they would create it cause they could not put back items on to the shelve as they were too busy, on the same day I then moved to Atterbury where I got assistance from the manager who was very helpful yet the date of the shower was incorrect, so when some friends and family used name to purchase they were told my register was empty so they used their discretion on some items and on some they managed to somehow purchase, yet some didn't receive gift receipts due to not being offered by the different shops and when I checked on register nothing was purchased, so I am stuck with double items. I have decided to keep the more expensive products, when I went to exchange for other items at the Atterbury I was refused though I was initially informed I could exchange items long as I had a register with the store. The assistant manager(Isaac Mokwena) at the time was rude to us, and this was our second visit as the first there was load shedding, and now I am stuck with items that are double and some triple. But when checking on the register the items are still not ticked off to show purchased items from friends and family. I only had receipts from some and was told I can't exchange the others, and I didn't want money as I explained but wanted to exchange for items not purchased.
