Getting a new fridge freezer installed tomorrow

Hello,

Anyone has had a fridge delivered.. installed amd old one taken away?

I am having mine delivered tomorrow but not sure if I should switch mine off from today and let it 'defrost' as I one of those old manual defrost ones.

Dont want be in a situation where they delivery guys refuse to take this old one away.

I still havent got a delivery slot nor I am able to contact the ppl I bought it off for guidance on this.

Please help! 🙏
