My Yahoomail Is No More Recieving Mails

Please can someone kindly tell me or help tell the reason why my Yahoomail is no more recieving mails here in Bangui. This incident started about a month ago. I can send mai through it but will never recieve mails sent to me expect spams. Is it due to the server or something/someone removing my mails? I can't understand!. Please I will like someone to tell me the reason why. I can't continue opening new mail address everytime.
Likewise can somone suggest any better mail to use apart from Yahoomails?
