Clearly customers don't come first

What a palaver to lodge a complaint online with Hewlett Packard SA. As is often the case, I have had to resort to Hello Peter. I have an HP Deskjet Ink Advantage 4265 and am outraged at how the price of replacement ink cartridges for this have rocketed in recent times. And I don't want to hear about the Rand exchange rate, about complicated loyalty programmes, etc. I want to be able to go to a local supplier and buy replacement cartridges at an affordable price. Also, I get thoroughly irritated when I get erroneous on-screen prompts telling me I'm not using HP products and warning me about the risks involved. I don't use generics. What does HP have to say for itself? This is all so annoying.
