GoAir — flight cancellation without prior information

Dear sir /madam,
I booked my air ticket through make my trip from delhi to chandigarh for dated 26.2.18 and my ticket was confirmed by your airline, but when i reached to check in on igi airport t2 in the morning of 26.2.18, i was told by your manager that flight for chandigarh has been canceled. I asked them why you didn't inform me and they told me that we called you once but ur mobile was off. I want to submit that may be my mobile was off but why you didn't send me any email or sms and added upon by the fact i did not get my refund till date. I suffered a lot due to this negligent and insensitive attitude of go air airline and i am seriously thinking of not traveling in future with goair air line.
