They are actually reputable but the problem is that you have been tricked by someone who is not a part of the company, you've missed it out and clicked the pishing site leading to such a scam.
Lesson #1: Don't easily click the link from an unknown person especially when asking for any information in regards to wallet access/keys.
Lesson #2: Don't easily trust people online especially if coming from a telegram group (unless if you know them) as there are many scammers around us.
Lesson #3: Only use and contact their support group when there is a problem/concern with your transactions.
Most newbies or even long timers will learn their lesson the hard way. And usually, it is already too late before they realize that someone who contacted them is not the official rep of the site.
I have experienced that a lot of times, though in different crypto exchange.
If you try to post in their official telegram group about your issue, someone will immediately contact you.
And the problem is, they are usually in disguise using the username of the exchange account or using the official logo.
Try to validate first if they are indeed part of the official admin group, check their official accounts and compare the username of that person.
Sometimes they are good in disguising if you don't verify their identities. And once you found out that they are fake accounts, one thing they do is delete their account.
That is based from my experience. So high likely that the OP was contacted by fake official account of pancakeswap and he fell for it.
