My tracking says my order was received and signed for last Friday (8 days ago) and i sill haven't even gotten an email saying they have even received my tests. First time I ordered with delta it was the holidays and It took 2 months for me to received my data. I was hoping the hollidays were the issue. Obviously delta leaf is under staffed. Looking like I'm about to have the same experience and just won't give you my money anymore. This is beyond pathetic. Luckily locally a DNA test company just opened up and they promis results in 48 hours which is what I expect. If I have to wait 2 months for results I might as well just sex test my self with light change because the time it's taking from delta is not worth $2 a test since in the time you guys I've again waisted 50% of my space and nutrients. Going to Google, yelp, Facebook, Instagram and evey other site that carries your name 1 every day until I get my results. I'm starting today with this but Monday I'm hitting google with a review describing this situation (I have 35k followers, and have had 140,0000 clicks on my reviews this month so far 😅) , Tuesday Facebook, Wednesday yelp, ect ect. As a business owner my self I know how awful bad reviews can hurt future and present business. Unfortunately this seems like all I can do to get any results from you guys.
