It’s not the first time Microsoft has shut down a support account on Twitter. The company shut down @LumiaHelp before when the Lumia brand went away. And now the brand is doing something similar with @SurfaceSupport, but it doesn’t mean they are shutting down Surface, despite its recent controversy. Instead, Microsoft looks like they want to consolidate their support account under one handle. The company is urging users to reach out to @MicrosoftHelps for any device or service inquiry.
