That's absolutely terrible.
I ordered this titanium canteen from Amazon, didn't realize until like two days after I ordered it that the estimated shipping date says it'll come in 3 months, a month-and-a-half in I message the seller, because the tracking says that it got stuck in customs and it hasn't updated in like 3 weeks.
The seller/brand name was iBasingo, within 24 hours they refunded me my money without any arguments anything other than the fact that I just asked them what is going on with my order. I would recommend this brand for their customer service but I would not recommend this brand unless you want to wait 3 months to get something that might not even show up EVER, lol.
I was actually going to buy a Twosun m390 knife on eBay for like only 80 bucks full titanium frame 3.74 inch blade milled frame etc, just an amazing knife. But I thought to myself do I want to wait 3 months to MAYBE it arrives? I'll pass.
I'd rather spend an extra hundred bucks and have a knife that I know I'll get for sure.
