Food Panda — milk shake at nine rupees voucher

Website: www.foodora.com

I have ordered a milkshake from food panda. The delivery person did not turn up to deliver me but the status is shown as delivered. The amount is also being deducted from my account.
I tried talking to the support team but none turned up. The offers in food panda are fake. They don't provide with the delivery person contact number to make up follow-ups.
