Call them and ask if the interview can be scheduled on Tuesday or Wednesday, and say that you would find it difficult to make it on Monday, without going into the reasons. You certainly should not say "I need more time to prepare", that makes it sound like you do not have enough confidence in your skills.
It could have been a scheduling mistake on their end. For example, the person who scheduled the meeting may not have read your mail, or typed in the date manually based on a misunderstanding of the day of week, or simply clicked a wrong box in the calendar popup, etc.
If you find out that the Monday interview was indeed intentional (because one of the key members of the interview panel was unavailable starting Tuesday, etc.), then well, you know what to do: either attend the interview on Monday or let go of the opportunity.
Do not make any mention of the mail you had sent. (
"As mentioned in my email, I asked for the interview on Tuesday or Wednesday, but I have received an invite for Monday.") Even if it is not your intention, it sounds like accusing the other party of not reading their email properly, which is not a great way to start an interview process. Just focus on what you want now, don't worry about what happened in the past.
