DrugBuyers.Com: Help - received seizure letter

Just received my first love letter. It gave me two options - to forfeit - check off that box - or to try and contest - did NOT check off that box - and sign my name and return which I did - with a note that website stated this was legal (order was for Valium). OK - at the end of love letter it says - future orders/seizures of controlled substances may result in significant fines or arrest. My question and worry is:

Last March ordered 90 Valium from Trusted meds - never arrived - they reshipped in April - that also never arrived - got money refunded - never heard a word from customs. Decided to stop ordering as I became concerned these just might have been seized. Then became "brave" again in July and ordered 50 from another website. Letter arrived today Sept 30th stating that seizure took place Sept 24th in Miami ( I am in NYC) and was for 100 Diazepam - none of these orders was for 100. Do you think that this was for the LAST order I placed in July - or for the ones placed last spring that never arrived - how long does it take these people to cough up the seizure letters. If for the one in July am not worried - because only order now from a place that ships domestically. However, if for one of the orders in the spring - then there is the outstanding order in July that never arrived and I am scared to death another one will come in 3 months for that and the DEA will knock on my door and take me away - I know - mind is running away with me.

Any opinions about this would be greatly appreciated.........
