Wasn't paid my salary after I finished my first month in my first job

Soo, I'm 21M and I have started working at a warehouse company last month. I was trained and always punctual with my work and when I clock in to work.

After we reached the end of the month I patiently waited for my salary to be sent to my account. I woke up the next morning and nothing was there. I waited until I have reached the warehouse and spoke with my team leader, they said that there were some issues with newcomers wages so they will be done manually for each one of us. I asked them if they could hurry as my rent is due in a few days and I need to pay my taxes a soon as possible. That and the fact Im running low on money for groceries and other personal things. They said that I would be getting it 24-48 hours tops. I borrowed money to get by for these two days but nothing was transferred. Last Friday, I spoke with them again, they said that we have already transferred the money and it should arrive by Monday next week depending on your bank. I contacted my bank to see if there are any pending payments, but they said nothing was there. I sent an email and a message through WhatsApp but no one replied. Now it's the weekend and tommorow is a bank holiday so I should be going to work on Tuesday.

I'm aware that there might be things that I should have done but didn't do and that is because this is my first job ever .

Please advise me on what to do .
