Brought cartridges advertised as Brother, what turned up was not Brother and unbranded. My printer does not recognise anything but genuine cartridges. Emailed Tonerink 3 times, rang twice, live chat once. No response to e-mails or online return link. I was able to contact via Livechat only to be told they couldn't give me a RA number to return because of present situation, yet were able to deliver under same conditions. Very frustrating to deal with and unresolved to date.
