MWEB LOST MY MAILBOX...

Got a Mweb account in 1998. Used my mailbox happily for many years. Tried to cancel once but they convinced me to stay for the mailbox sake. Two months ago I phoned them to upgrade to Fiber. Should have known. Instead of upgrading they created a new account. For two months I had two usernames. And then they cancel old username and gone is all my email. What a sad case of affairs, Their call center is most probably the worst in the SA if not the world. From sales to Technical they go in circles. And if they do not like what you say they let you hold on until you realize they are not going to help you any further. And do not ask for senior people to contact you. That does not happen, you just go on hold. I am still holding on to see if they can get my mailbox back. Any suggestion on a good Fiber ISP?
