Not getting paid during my holidays

Hello,
due to payment schedule, which was displayed by my employer, I should get my salary today. However after checking my account, it was not there.

I am on my holidays now and on my notice period as I got a better job offer. I am not coming back after the holidays finish.

When I called HR department to ask about my salary, I was told that I would not get paid this week, because I am on holidays, so they cannot pay me.

Is it legal? Have never ever met with such a situation before at work.

I analyzed the contract again, also the handbook for employees and it just confirmed what I remembered - there was nothing said about n o t paying employees when they are on holidays.

It is especially frustrating, as I should pay my rent soon (before the next salary payment date) and my landlord is very strict about doing it on time. I informed a person from HR about it and it was obviously ignored.
Another thing is that if the two payment will be joined, I will have to pay a higher tax.
