This number comes in more than 5 times a day, no one is there. Even calls at 1am, not pleased at all! Calling to get the number blocked tomorrow. enough is Enough!

got call recently a few times a day, I answered one but no one replied. it is weird!

Same thing .. no one replied when answered..  I got call 5 times today and each time no reply when answered.,..Caller name display on the phone  is Doctor Group..

Same thing, phone rings noone responds when answered.  Might be bot testing numbers to see if there is a time the phone gets answered.  They then sell these lists with a best time to call response.  If you see the dial display, do not answer.
