Oculus does not provide phone support, and I removed the info above as it won't help you (and will only frustrate you and our non-support staff). Please wait for Oculus Support to reply to your request via the web form. Thanks. https://support.oculus.com/
Eight working days for me, if you count Saturday as a working day, which as I've received responses from Oculus Support on a Saturday it evidently is.
Why can't they at least give us an undertaking to deal with problems in a reasonable time frame, and stick to it? As it is, there's no sort of service standard. It seems to be an utter disaster over there, and has been for some time.
Sure, technical problems take time to analyse. But if adequate information is being collected by the software (and if, by default, it isn't, they can always email out more detailed collection tools to customers with issues) then surely they can't need an indefinite amount of time?
