Former Verizon customers who were switched over to Frontier Communications on Friday are still reporting outages and other problems today.

Verizon sold its FiOS and DSL networks in California, Florida, and Texas to Frontier, but the transition has not been smooth. On Friday, Frontier acknowledged a "technical issue" involving the integration of systems, but the company said it had been fixed by 9:30am ET that morning.

That assurance seems to have been premature, with customers still reporting problems on DownDetector and Twitter throughout the weekend and today. "Onto the 4th day without Internet or any working account...any timeframe guys? This is getting really crazy!" one California customer complained today.

@lorenv We are working to get all services restored as soon as possible. However, I do not know of an exact time ... https://t.co/j1JIyv9Qg0 — Ask Frontier (@AskFrontier) April 4, 2016

In addition to service outages, there have been account-related problems. For example, some customers report that they are not receiving TV channels that they subscribe to.

@laurel_joe We do apologize for the inconvenience. We will have you up and running as soon as possible. Thank you for your patience. -T.J — Ask Frontier (@AskFrontier) April 4, 2016

Other customers reported being unable to watch on-demand video.

An unrelated fiber cut in Tampa, Florida on Friday added to the problems, but that doesn't appear to be the primary issue. California seems to be getting the worst of it based on Frontier's service status map. The map shows outages in California but not Texas and Florida. When questioned about this on Twitter, Frontier said, "Unfortunately, the map only represents widespread outages. Individual outages are not shown."

We're trying to get more information from Frontier and Verizon and will provide an update if we get one.

A similar problem happened when Frontier bought former AT&T territory in Connecticut late in 2014. Frontier messed up the changeover in that case as well, leaving some customers without service for weeks.

UPDATE: Frontier responded to Ars, acknowledging that some customers are still affected by problems but that the company is "making progress in areas where customers experienced service disruptions on a variety of levels."

"Given the complexity of the transaction, disruptions are not unexpected but they are never welcome and we have apologized to affected customers and are working around the clock to address all issues," Frontier said.

On-demand video is now available, and Frontier is "resolving outstanding issues" related to its online account system, a spokesperson said. "We are making solid progress and look forward to business as usual for all customers in the very near future," the company said.

Verizon had no comment. "Verizon’s role in those properties ended on Friday," Frontier said.
