The sellers are permitted to add time to your shipping time as they please. So their 60 day guarantee is a lie. The sellers are also permitted to advertise faster shipping for an increased cost but do not have to honour it. You can't contact Ali express to argue anything without using the auto system and it just sends you in a constant loop of telling you to wait 10 days. And 10 more days. And then 10 more days. So basically sellers can steal your money and there is nothing you can do.
