I thought it was common knowledge that Mike has health issues,

and does go and have treatment at times so this obviously delays orders..

I wouldn't say it is common knowledge.  I have ordered from MAD more than several times in the past before he deleted my account.  I heard many excuses as to why he hadn't processed or delivered the order such as bad weather had stopped the postal service, USPS online service had gone down, email problems and the BS kept coming.  Not once did he mention poor health as a reason.  If he had of, I and most others would have been sympathetic and understanding.  To abuse customers or just refuse to answer their queries is just plain bad form.  He has lost a huge amount of business around the world due to his poor communication skills.
