Review Did not provide voucher within agreed time frame.

I ordered from a restaurant and foodpanda was not able to deliver it on time. The food was supposed to be delivered in 30 minutes, but I waited for an additional more or less 30 mins for the food to arrived. So I chatted with the chat support representative and I was told that I'll be contacted through email within the day regarding my voucher for the delayed delivery. When I got the email from foodpanda I was told that I'll be receiving a 48 php voucher within 24-48hrs, however, no voucher came and the worst part is, this happened again the following day. This incident happened consecutively and I now I requested to speak with a manager or a supervisor but I never got a call. Instead a representative (not a supervisor or a manager) called me. The representative who called me was very rude. I can't even get a word in because she always cuts me off, and when I insisted to speak so that I could explain what happened in hopes this never happens again, she hung up on me.
