Got a postcard just like all of the above and also another one that stated to call another number to claim immediately, it also have a parcel number
Postcard looked computer generated and not real plus I don't know a Mrs. Carter. Didn't call any numbers dumped in trash.
I got a yellow card. They knew my name and address. I called and the sales girl tried to flatter me about my accent. Something about water softeners. Anyone who "cons" me into calling them with pretend hand written cards gets no sale with me. Stuff them! Envirotech eh? (Apparently on BBB) ... they can have one of my nice letters warning them not to send me mail or I will invoice $40 per item for receiving, reviewing, shredding and removal. Perfectly acceptable, with late payment clause too. Could be a nice earner if they don't delete me off their list. Vermin in my book. If their product was that good, it would sell itself without junk mail.
I receive the same post card by Mrs. Carter. What got me curious when it said " We have recently been trying to contact you". I'm glad I read this post first before calling.
