A few years ago I placed many online orders with Walmart. Mostly clothing as they had incredible sales on that. Never had any issues until the day I got shipping notices for several cell phones I didn't order. Someone hacked into my account on Walmart and ordered a bunch of those prepaid phones where you get a phone card emailed immediately. I checked the email they gave, which was listed and it was chinese.
Then I had to go through the trouble of refusing and sending back the phones as they for many of those orders were so fast that I could not cancel the order anymore.
Unfortunately customer service was not really helping me out much and were quite rude. They then just cancelled my account period so I couldn't even order anymore without notice.
Unfortunately, I needed online order as often the size I needed, especially in jeans is rarely at the store itself. And the sales. Oh well.
At least with Amazon I know I get great customer service, but I can't get the deals on clothing there unfortunately.
They did just built a brand new Walmart right across from me, so I could technically just walk over there. If I survive crossing the 6 lanes that is.
But they had sales online they never have at the stores.
