Hung up when I answered

Well this one has been busy today... I missed a call also from this number so checked on here before calling back

answered but hung up

Busy tone when try to return call. Spam caller

Caller: I don't know

While mobile was ringing, quickly checked this website - saw others had complained, I didn't bother to answer. Figured if the listing here was incorrect, the caller would leave a message. No message received. Guess it was a TMrktr.

Same as you Mr. Anonymous - got the same call today.

I received a call from this number, no message was left. Tried calling back, number engaged.

I didn't answer, didn't know the number. They didn't leave a message.
Assumed it was spam. The Previous poster confirms my assumption.

hung up. When I rang back phone cut out
