Spice Jet Airlines — sg167 dtd 04 may 2019

I was told the flight sg167 dtd 04-may-2019 got cancelled due to technical fault. Full refund was agreed & i was issued another ticket on next day flight. I understand it was wrong information & the airline has tricked me since i can see on your site that the flight took departed bom & arrived cok on time & as scheduled. Why was i tricked? I need solid answer to this. I & my family (Including children) had to face lot of difficulty due to this.
