I am sorry. I have looked into this, and it looks like Royal Mail has not delivered this. Normally, Royal Mail takes 2-3 days on average. Both Royal Mail and DPD have well over 99% success rates. I have now resent this order again.
I am told by Royal Mail that their tracking has issues on a small number of some devices but a fix out any day.
Regards
“Good service from Plumbinbits, albeit comms were confusing with 2 messages on different days saying items now been dispatched. Delivery took longer than anticpated but that was more likey Royal Mail issues. items OK, but pricey for a simple washer again i know Ideal Standard items are overpriced compared with other brands.”
“I was looking for a connector for a wierd thread tap flexi and I had tried a M10 and a 3/8 bsp but I was convinced it could only be 1/4 bsp so I ordered it. It arrived in really short time but alas, it was still not the right thread. I couldn't fault the service from plumbinbits. I just couldn't find the right thread. Thanks anyway.”
