Sales compared to service?

I went into the Kya Sands branch to purchase bathroom accessories and unfortunately they didn’t have the one product. I was asked to pay for the product and they would order from Lonehill beginning of Sep and let me know when to collect. After a month I went back and all I got was confused looks. Then I went to the Westgate branch where we bought quite a number of stuff for renovations where I left my proof of payment for that tumbler with Anderson. Up until today I had no feedback. On Monday I went back to the branch to make more purchases and was told by Lihle that they would receive the stock that I needed on Thursday. Friday she gave me a call and said that they supplier didn’t have the items that I needed and if I want it ordered from other branches I had to pay up front like my previous order that I still didn’t receive???? I requested for the branch manager to give me a call as I am not prepared to make the same mistake again but to no avail. Obviously customer service is not important to your company?
