Pathetic staff service Pick N Pay Clothing Stores

I am 9 months pregnant and I purchased a dress from Pick n Pay clothing in Greenstone mall, they did not have my size so i took the dress there and they asked me to go to pick n pay meadowdale which i did and upon arrival they did not have size L in the dress they only had one which was damaged and didn't want to sell it. Meadowdale then referred me to eastgate mall where they have a bigger stock. I then called Pick n Pay Karaglen being closer for me to travel in my current situation. I asked if they could please courier the dress for me from Eastgate mall to here for me to collect and they refused. This is such poor customer service as the staff at the stores are so unhelpful and don't care that they send customers who is heavily pregnant around the show like a treasure hunt. Pathetic and disgusting service from unhelpful staff at all three stores.
