Bottles App - No Delivery and Terrible Customer Support

I am writing this review here, hoping SOMEONE will bother contacting me! I ordered a few groceries on the Bottles App on Monday afternoon (order number ***). They were never delivered. I e-mailed customer support. I got a ticket number but no response. I phoned the customer support numerous times on Tuesday and finally got through in the afternoon. I was told the order showed delivered. I explained that it certainly wasn't delivered to me. I have not heard one word since! I tried phoning today again and the phone just rings. I tried e-mailing again. No response. I will never use this app again nor recommend it to anyone! Absolutely shocking! I would appreciate it if someone could look into this matter and refund me on an urgent basis!
