Unfortunately we do have a handful of products that are on a pre order bases from the suppliers, moon slate is one of those products. We can only update you with the information the suppliers give us, it is normally an estimate.
We had called you on the 17th March to see if you were happy to wait, we offered a full refund or an alternative we do have?
It is due soon, and i will call to arrange a suitable delivery for you. In the meantime, if you are unable to wait, just give us a call, and let us know how you would like to proceed.
Thank you for your feedback
