Very dissapointing service and possibly a ****

I had placed an order which was only partially fulfilled. I sent an email to report the missing items to which I did not get a reply. Ultimately I was able to chat to someone on their web site who told me that the item was out of stock and they expect to have stock in a day or two and will contact me. Nearly 3 weeks later I have not been contacted and have not received the outstanding items on the order. I have emailed again and have sent messages on Facebook and on their web site chat. So far I have not received any response. I will update my experience once I have received a response, but at this stage I can only caution against using thedogfoodapp.🤨
