Poor customer service with inconsiderate lazy staff

Visited the branch to change my wiper blades. I was told if they have stock, they can replace it under motorplan. To facilitate the process, I had parts department confirm they had stock of the item. Was told to wait 15mins...which turned into 45mins since there is only 1 person that can assist. After 45mins, the employee (Wiseman) inspects my car then tells me he cannot sort it out. Says, that despite it being a quick request, he has to do paperwork and it has to go through 4 steps, and I should come back on Monday.

I find this totally ridiculous, considering wiper blades are a safety threat and the fix was very quick...2mins (at most).

Sadly this is not the first bad experience with this branch.
