The last Halfords order was for fork oil. The store rang me to say it was out of stock but they would order it in which would take about 3 or 4 days.Kwik fit is on my 'never to be used again' list along with The Carphone Warehouse 😀
Like you say it's probably a bit like Halfords, where some branches are fine and others downright terrible.
No further messages so 9 days later, I cycled there to collect and was told unfortunately the stock levels were wrong so it had hit a limbo. I got a refund.
The next day I checked and with stock still showing I ordered again. No messages at all so a week later I called in and surprisingly it was there for me. Random communication seems the norm everywhere Halfords north east.
