Endemic problem of bad service on shop floor

I dislike shopping at Builder's Warehouse because I can never find anyone to help me. I tried the new 'help' station at Fourways a while back and there was absolutely no response. I was in the Norwood branch last Friday and there was NOT ONE person available on the shop floor. I spoke to the lady at the information desk and she admitted that there was a problem and she very kindly went to look for the item with me. The manager was hanging around in the background while I was complaining but after I had paid he had disappeared upstairs. If and when I do find someone, they often just point me vaguely towards another aisle or just give me the aisle number or yell to someone else to sort it out. The shop assistants' product knowledge is often poor to non-existent. All of this is particularly irritating when you do find assistants, and they are hanging around the paint desk (a favourite spot for relaxing and gossiping it seems). All of this applies to all three branches that I frequent, namely Fourways, Sunninghill and Norwood, so much so that shopping at Builders is something I try to avoid as much as possible. Which is difficult because you have cornered the market but I will seek out a branch of Leroy Merlin or Micah if I possibly can. This has been going on for years!!!
