Faulty black ink cartridge

HP DeskJet 3730
Microsoft Windows 10 (64-bit)

Hi, I am enrolled on Instant Ink programme and am having problems with print quality for black ink. The black ink cartridge is nearing empty but doesn't print out any black , I have tried all cleaning / alignment etc to no avail and all the test pages etc. I have not got a replacement  to switch to and this cartridge is approx two years old 

( the only one I have had since Aug 2017 ) There is no replacement pending and I cannot find any way to contact Instant Ink to request a replacement.

Please let me know how I can have replacement for the black cartridge.

Thank you 

Best regards
