I understand that you're surprised, but fact to the matter is that we have lots of orders awaiting the receipt of payment and up to the last moment current available stock may be unknown when it comes to items with low availability. Such as you have purchased.
To make things worse both items that I suggested replacing (Dimmer and Wall Plug) are end of life items and it's not possible to run regular prodction any more. Soon they will be replaced with new items and such problem shouldn't repeat. However, knowing that lead time for new devices will be longer than initially expected I suggested that you replaced them with some other items instead of waiting a few more weeks.
Anyway, explanations aside, I should have the missing devices for you tomorrow afternoon. If that's the case, I will send your order on Thursday.
I'm sorry for inconvenience.
