PIVOTEL SATELLITE PTY LIMITED, is the holder of number allocations 0488 800 000 - 0488 899 999. They run scams, but most importantly IMSI call interceptors (yes people can easily intercept your calls, texts and track your physical location...but guess what the Australian Government doesn't mind...sad but true) from there number allocations, they have been fined by the federal government and failed to pass review requests back to other Telco's and the government...but they still own their number prefixes and operate in Australia...should be able to block number ranges on your phone not just one number at a time. If you receive a call 0488 8 and any numbers after that ignore and block it.
