Harrasment & unsolicited calls

Never requested callback from hippo but yet getting more than 50 calls even after asking call center clowns to remove my number. App installed to block all calls and see them trying to call more than 10 calls at random times. Avoid this "company" at all cost as they will probably reply with we have strict control of calls....bla bla bla when the truth is they have no control and allow their system to harass users with more than 10 calls a day for weeks.
