Scam/Fraud
26 Jul 2025
This number is no longer associated with Colt Technology Services. It’s now being used by scammers impersonating Three (3) – though they oddly refer to the old Hutchison 3G branding, which hasn't been used in years. If you receive a call from this number, do not share any personal or account details. It’s a scam – plain and simple. Block the number and report it. Stay vigilant and spread the word.
Caller: Some Indian women
