Cant activate phone / port old number

Hi, im having problems activating my Samsung A50, Im trying to bring a number from Sonetel which allows porting of numbers but it isnt activating through the website, and I tried with customer service agent last night and he said they were having general technical difficulties and to try later.

I have now tried to launch the chat support feature on the website and thats now launching for some reason.

Can anyone help me activate my phone and port my old number ?!
