What’s going on with the frequent “typing errors”?

Dear, hello?

Mr. Qian, a citizen, has been troubled recently. His mobile phone received some strange calls for no apparent reason as soon as he entered the nightclub. At first he didn’t take it seriously, thinking that someone else had “made a wrong call”, but for more than half a month, his phone kept ringing with unknown calls, and these people all said they were dialing Lucheng District’s 24-hour square dance complaint acceptance hotline 55566591. How could the Square Dance investment hotline number be transferred to Mr. Qian’s mobile phone?

Citizens complained about square dancing, but were told that the number was "wrong"

This 24-hour complaint hotline seems to be in a set mode and is normally connected during working hours, but when After get off work hours and weekends, the call will be automatically forwarded to Mr. Qian’s mobile phone. But starting from the day before yesterday, at 9:26 a.m., the reporter called 55566591 again and found that even on working days, the call was received from Mr. Qian's mobile phone. It can be said that Mr. Qian's mobile phone has become a "complaint hotline."
