I am trying to purchase items for pickup on websites at places like Best Buy, Target, Walmart, Home Depot and Lowes. I purchased about 500 dollars worth of things on both target and home depot (not at the same time or day, one after the other because the first i tried didnt work) and it said it went through, gave me an email confirming it did go through and then about 4 mins later it sent an email saying that the order was cancelled. So once again i tried to do the same thing with target but using different a different card/account and it did all the same things : went through, sent confirmation email, then a few minutes later sent a "your order was cancelled email" but this time it said there was a technical issue.
Why is this happening can anyone help me?
I even tried to buy other things to bring the total down but nothing worked.
I am fairly new to this and I just really need this to work for me because im broke, have invested alot of time into this atp and have kids to feed and bills to pay. I thought this would have worked out by now. I dont have anymore money to invest in this unless it works and i can put back in and the same with time. Please help, thank you
