Email dont work

Ever since you moved my email (sgarcia@marine75.com) to roundcube it just does not work anymore.. I keep getting the following message: 'Homestead.com is not responding due to a long running scrip' I called several times to 1800-710-1998 but nothing has been done to resolved this issue. . I am so frustrated that im about to close this account i have with homestead for about 15 years. Marine75.com
