Scam/Fraud
20 Sep 2025
I got a call from this number and she said it's from Three. She offered a discount on my phone plan and started to ask some questions like how much do I pay for my phone plan? I said if you are offering discount on it, you should now how much do I pay. She said we have all your details. Then I repeat if you do, then you should know how much I pay monthly. She just get lost and finished conversation
