just got fired

feel really shit rn. just got fired from a really good company - for the most stupid reason too it felt like. I'm an sdr and apparently a customer complained about me because i was rude on the phone, even tho all I did was handle objections. i loved the job and the product, i was 149% on target this month, i come in early and leave late everyday, and still they did me like this. any words of motivation would be appreciated.. not sure how to bounce back
