Who called from 7783224767

unknown number called

Been getting abusive messages from this number for 3 weeks.
when i call it it just rings out.
i googled it. said it was connected to hayvari. an indian uni site... i dont know anyone in india!!

I meant 3 months. not 3 weeks. just in the last 2 weeks it has gotten really bad and alllll the time.

I received a txt message from this number on the 20th February. I don't recognize the number but it caused a lot of  problems in my home due to the nature of the message.
