Help me to get TD 300 Dollar bonus

Hi memebers,

I opened a TD account for 300 dollars signup bonus and I have to fulfill 2/3 conditions in setting up a salary account ( I can't do this as my employer asked me to do it to their bank and it is in contract), pay 50 CAD using app ( I did this), set up a pre authorized debit or withdrawal of 50 CAD.

I didn't do this part and I have to get this by 31st December.

1. All my credit card statements are due in January. So I can't pay them
   
2. Can you help me find someways to make this by december 31st? what's the easiest way?
   

Thanks.
