A week ago we noted that a Mediacom e-mail upgrade promising to deliver "next generation" e-mail service wound up leaving some customers without e-mail for a week. We're now two weeks since the upgrade, and both residential and business users are still writing in to complain that they're either without e-mail service, or they're suffering through oddities like lost e-mail. An ongoing thread in our Mediacom forum has hit 55 pages, most of them filled with customers complaining about the broken upgrade.

"I have a friend who is missing around 1200 e-mails because of this," writes in one user. "This is her business account and the missing e-mails contained crucial information," he says. "She is about to lose a $30,000 account and may have to shut down her business permanently if she does lose the account and doesn't get the information back by next week."

"I am still without-mail service as of Tuesday, December 22," says another user. "No one at Mediacom is helpful," he writes. "On the 18th all of our accounts seemed to be working, now they are not," writes yet another user. "The 18th is the last time we have been able to receive from these accounts."

The upgrade appears to have given spammers an opportunity to hammer the system further, complicating the upgrade and repair process. Several customers complain that of the e-mail they do actually get, a chunk of it is new phishing attempts they hadn't seen previously. Meanwhile, Mediacom appears to be waffling on user service credits -- at least according to their official migration website and FAQ, which tells customers refunds may or may not happen after the company figures out what's going on:On the positive side, Mediacom has several helpful techs in our forums (like MediacomJasn ) that are trying to assist out individual customers where possible. Unfortunately, that doesn't appear to be making Mediacom's back end problem resolution go any faster.
