Shocking online and instore service

I checked Leroy Merlin website for a mosaic tile I wanted. Went to Greenstone branch to get it. They had only 1 in stock and I needed 4 boxes. The lady who worked in that section (when we eventually found her) was totally unhelpful and didn’t offer to see if she could get from other branches. My daughter then checked the website and saw that Fourways branch had in stock. She went there and same story. No stock, even though advertised that they had. She then asked the guy if he could get from another branch and he said he would see if he could. 10 days later I am told that they don’t have. When my daughter complained about the service she was continually cut off. This is shocking service from a firm who professes to be so wonderful but fall down miserably. I don’t think I will be shopping there again.
