Hello team,

Sir my complaint is that, I have ordered a mobile phone cover of honor 9n mobile two days back. And yesterday I got a message that your order is processed and will be shipped within 72 hours.
But today I received a call from a number and he is saying that he is from stayclassy and he told me that your order is canceled and for refund you have to follow some steps. He also added that you will get a message of cancellation after the refund will added to your account. I have done all the things he has asked me to do, but the whole money from my account is deducted. He had told me that the money will be added after cutting money from your account. And he asked my paytm login details etc. Then he said that he want SBI account for that. Because the money is in hold and only in SBI account he can refund it.
Sir the amount in my account was 4797 and the phone cover was of 199 only.
Now his mobile is switched off. I don't know what to do know.
Kindly take a strict action against it. I am a student and this money means a lot to me.
