Less than a week of the switch from Special Delivery to Recorded Delivery and you have got 2 bad reviews so far. People have no mercy, i would suggest removing the 'Special Delivery Guaranteed by 1pm' on your listings if you are no longer offering it.
I got a half ounce of your Rolex (amazing stuff) and i did not even bat an eyelid at it getting sent recorded instead of special. Makes no difference to me. I still left a 10/10 and did not even mention it, the only reason i am bringing it up now is because of the bad reviews i saw and there will be more incoming, unless action is taken, i can assure you. You don't deserve those bad reviews so soon but if the changes are not made then you will deserve nothing less, because for many the Special by 1pm is the icing on the cake.
