The caller with the number +6492005031 is likely a telemarketing firm, as one of the users reported that reverse calling the number revealed it to be "Raisers Hub", a firm known for cold calling and tele sales. Although some users were unsure about the identity of the caller, the fact that they did not leave a voicemail message suggests that the call was not of utmost importance, which is consistent with the behavior of telemarketers. The lack of voicemail from the caller led one user to block the number to avoid future harassment.
An unknown cell call went unanswered. If it mattered, a reputable business would have left a voicemail, unlike this number. I'm blocking it to stop further harassment.
I called back and discovered it was Raisers Hub, a telemarketing company.
I'm unsure who this is, sorry, but I've gotten several calls from this number.
