I received a package on 11th of july, i received a wrong box with my AWB number stuck on it. The box is not mine. They exchanged my package with someone else. My package had to and from addresses written on it. It had name and phone numbers as well. I have been mailing them since yesterday but no proper response. They asked me for a picture of my package, i didnt click a picture before sending. Why should i? I sent them a picture of the wrong package that i recieved. I requested a call from them.. but I didn’t get any response. Kindly look into this matter.
