How to get accidentally delete messages back?

I was in a huge group chat with friends, so I got a lot of messages. I put it on do not disturb (I have an iPhone) and accidentally deleted the chat. Now i can't get the new messages because it's on do not disturb. Is there a way I can get it back?

Call your local service provider

You can't get back messages that you've missed or deleted. Messages are not like emails.

If you have a Mac and your messaging is connected you will have the messages on there. If not, there's no way

You can't. But theyare stored of the card.
