I have huge and returning problems with iCloud. I cannot send e.mails and there is nothing wrong with my settings. It started yesterday. Does anyone no the reason?

What is wrong with Apple. This is the third time during autumn, that I experience problems with icloud. Apparently yesterday once again there was an outage with icloud and the problem was solved, but NO it is not solved. I still can not send e.mails and I am probably not the only one. Each time I talk to a technician from Apple, the only thing they do is to uninstall my icloud and reinstall it again. With no results. A waste of time. Please make your system work and give a better support. Who do I call to get a proper assistance???

And why can I not select icloud under my products??
