Customer service hung up on me on the phone - Consumer Complaint for FoodPanda - Head Office

I requested to receive a call from foodpanda about a voucher that was not sent to me within the agreed time frame. I received a call from a representative at foodpanda whom was very rude and wouldn't let me get a word in our conversation. Then, when I insisted to speak she hung up on me.

I've attached the call log and the phone number the foodpanda representative used to call me

PS: you would see 2 call logs from foodpanda because during the first call I received from foodpanda, I requested to be contacted again after several minutes because I was in the comfort room.
