Blackberry is on Twitter and that's great if you are too (we're guessing you are since you're here). Generally, companies respond quickly to customer requests made via Twitter because they know the conversation is public. However, many customer service teams are not equipped to actually solve problems over Twitter and they will often reply quickly to tell you to call or direct you to their help desk. We're not saying that Blackberry will do this, but don' be surprised if they do.
One thing you might like even more than trying to tweet or DM Blackberry your customer service problem is to use GetHuman's problem-specific help tool. For companies and problems where phone is the best or only way to deal with the issue, we give you tools to get through to a rep as much as 75% faster. But for companies like Blackberry that might not have a phone number, we also provide tools for getting their attention on Twitter and linking back to a page that you own on GetHuman's website. The nice thing about that is that you can track views of other customers on your own page, which is something that Blackberry's personnel would be able to see as well, meaning that you can share and publicize your issue to get attention faster.
Of the 4 way(s) to get in touch with Blackberry, customers like you claim that the best one is the 877-255-2377 option.
