364 black ink problem

HP Recommended
Example: Photosmart c309g

Hi, I have the hip photosmart c309g model. I buy the multipack 364 with the three colours and the larger black cartridge. This multipack does not contain the smaller sized black ink. The printer needs both......don’t know why. My problem is I can buy the smaller ink anywhere not even up do it. I’ve been on the phone most of the day with them. Can anyone help me I’m desperate to get my printer up and running till I can afford to bin it and replace it.
