LACK OF ASSISTANCE WITH A PHISHING ATTACK

I have had an internet account with MWEB for many years and I believe that this account has been hacked through a Phishing attack. I have tried my best to recover my account for the last 3 days without any success. I have held on for Technical Support for hours without any luck. I have logged queries; no luck. I am extremely concerned by the lack of response from MWEB regarding my Phishing problem; please help
