Bottles App delivery disaster

I placed an order early this morning and was delighted when it arrived at around 10am, in plenty time for me to use the groceries I'd ordered to make lunch for the family. Imagine my disappointment when I realised I had received the wrong order. Not to worry, I thought, mistakes happen. I notified Bottles immediately via email as no one was answering their customer support phone number. I then eventually managed to get hold of someone on the phone just under an hour later. They were extremely apologetic for the mix up and promised to figure it all out and get back to me. All sorted, I thought, but gosh was I wrong. I have had no further response at all, no follow up call or email, just radio silence. No one answering phones or emails the rest of the day and I am still sitting with someone else's order and not the food and other groceries that I ordered and paid for. I am so frustrated by the lack of communication and the fact that this hasn't been resolved. I spent R850 through the app and a day later have still not recieved my order nor has the wrong order been collected and I have used lots of airtime trying to contact the call center. I won't be using this app again. Checkers Sixty60 is much more jacked up, have never had a problem with them.
