NO GROCERIES AND NO REFUND-SCAM

There is an app that you can download called Grocer. They promise to deliver you groceries within 60 minutes. So on the 7th January 2021, I ordered items on this Grocery app called Local Grocer App. It is now the 9th January 2021 and I still have not received my groceries. There are no contact numbers besides an email address which does not work. I really struggle badly as a single parent with a daughter so for them not to return my money or deliver my groceries is a big issue for me, I found a support e-mail address on the app but to date, I have not even had a reply. Do not download this app or order online as I do not know if it is a scam or not but something is wrong as they have no contactable numbers This service is atrocious and they are not customer orientated.
