Sunrise Sports India — Astrox 100 Zx/ Crack on the frame

I bought a Yonex Astrox 100zx 3 weeks ago. I gave it to be strung on 25/26lbs. From the second day the head of the frame was elongated. The racket really felt horrible to play like that. However, after 3 weeks of arrival, i found the frame weakened. So I had cut the string. The frame didn't exactly cracked. But the painting started to crack. I used a yonex racket before. Never had such issue with it. I gave it away when bought this. I was excited to play with it. Unfortunately it didn't last. I don't have anymore money to spend, I'm student without a job now. I really hope you understand my situation and give a replacement. I tried to add a picture. But it kept showing it is too large.
Thank you
