Hi, can anyone help or advise. I referred a friend and they placed an order via the link I sent on the 22nd of the march as the eufy app said I would get an £80 Amazon voucher if order was placed on that day and they would get a £40 discount which they did on frienduk code. It then says I will get a notification someone has used the link and after sale and cooling off period I would get the voucher. The think is I have not received any notification after 10 days. Is this normal or have I just wasted my time.
