Fraud mobile companies!!!

Hi,

Greetings!!!

I got a call from alive company that they have a deal for me, they will provide me 4g phone with 16 gb memory and a deal for power bank as well as provide net pack for 3 months. But this is fraud at all. This phone is not 4g at all and they didn't make recharge yet. I am calling them on daily basis but now even they don't pick the call. What should I do.

Regards
