The installer noticed that the extractor fan was missing (see final paragraph of Phone-calls...) along with the 3 spotlights, to be embedded in the ceiling. The paperwork included their installation, but the items had not been added to the order.
I called our bathroom designer, on his mobile. He said that he could arrange for the missing parts to be collected from the store at 50% discount, given the error... Except that it was his day off. So, I called the B&Q store directly and spoke to someone who said they'd have to speak to colleagues in the HomeFit department before she was able to help. We selected & chose the items we needed, so that when B&Q called back we could place the order, ready for collection that evening.
I headed to B&Q at about 7:30pm. I picked up a few extra bits to make the new bathroom as nice as possible, then made my way to Kitchens & bathrooms. Sure enough the items were ready for collection. £100 later I was heading home.
Unfortunately, we found out the following day that I had been sold incorrect parts - light bulbs & their fittings unsuitable for the bathroom. This was despite our installer speaking to B&Q directly.
Our only option was to head out again & try to purchase the necessary kit. However, our installer offered to buy the parts and bring them the following day. Problem solved...
...or so we thought.
