I put up an ad to sell a car. A person messaged me on pakwheels giving an offer. It was 12 am so I didn't reply at that time but I clicked on the I button in front of his name thinking it would be his info .. but when I pressed the i it went red.. now I've sent him some messages but he hasn't responded.. can anyone tell me the meaning of a red i/!.and I also can't press the i again
