Other. I had a delivery driver knock on my door and leave me a note from A+ delivery services giving me a reference number and then giving me a telephone number or a website to contact which is www. a+delivery. net and then when I go there it says possible scam, alert, or their certificate isnât correct and then it gives me a number to call at 1-800-691-0591 and when I called them about this delivery being delivered to me, I asked what it was? Theyâre trying to deliver something that requires a signature, but then wouldnât tell me what it was, I did not give her my information to try to set up some type of delivery because she couldnât tell me what they were delivering so that just sounds crazy to me! Report this in case of something serious or strange, if legit they should be able to tell me!
