The last compatible toner I purchased for an OKI MC 851 does not work - what can I do about this?
Hi there. I believe it was a black compatible cartridge that you purchased. I will get one of our customer care team to get in touch right away. If we can't resolve the problem that you are having over the telephone we will arrange for a collection and replacement cartridge to be delivered for you. I will pass on your details right away. Thanks, Stu.
