bad service

I contacted Groupon to relist an item I had listed in the past. I was told they can no longer list this specific item and was asked what else I had. I told Carl I had baby grows and he said he was interested. I sent all my images and stuff to him and asked him to come up with a price for me after he bashed my pricing and told me what he thinks my product costs to manufacture. Then nothing. I mailed and mailed and eventually called him and he said when I send a mail I must call him too. He told me he was busy with valentines and would call me the next week. 5 weeks later I called him back. He then negotiated my price down to almost zero, asked me to send my stuff and again no reply. Everytime I need to get hold of him I have to mail Brendon. I eventually had enough and canceled my listing that I've been trying to get done since Jan and Brendon mails to apologise and try help. Nothing from Carl. Never says sorry for his shocking service. Carl takes bad service to the next level!! In what business do you have to phone someone yo inform them you have sent an email and ask them to please read it.
