I have had over 15 missed calls from this number in the past two weeks. First called 22/07/25 I answered, it was a lady with a strong accent said I was a loyal customer so was giving me a £20 voucher, I was in a meeting so hung up. This number has continued to call me I answered again today was same lady but with a different offer was offered iPhone 16 for £30 a month unlimited calls, text and data asked what I needed to do she said sign up today as its only on for 2 days. Find this offer too good to be true so hung up and blocked the call.

Lady with a thick accent called said she was from Tesco Mobile and I was a loyal customer. Said I would have £25 discount and asked if I was keeper of the phone number. Said yes and was like I shall send a link for you to fill out, I then hung up and she called again and I didn't answer. No voicemail ect was left.

Called. Didn't leave message, therefore NOT important. BLOCKED

Miss the call and rang back, went straight to a lady with a heavy accent. Said they was O2 and as a loyal customer I got a £20 gift voucher, said to transfer to the correct department. Didn't stay on call further, they tried ringing back. Suspicious and avoid.
