I saw a home furnishing on their page and in comment section many people were asking for price and they had replied with the phone number and I texted on that number and booked the furnishing piece i liked. But now after two days I'm seeing that they have turned off the comment section and i texted on the same number with my brother's number and confronted him about scam and he accepted but now he isn't refunding my money.
