Ubereats missing items/no invoice received

I ordered KFC through Ubereats today 12/12/23. When my order was delivered there was only 1 burger in and I ordered 4. I tried to check on my ubereats account for my invoice, but was there no trace of my order. I contacted KFC Akasia and was informed that they also do not find any order from Ubereats. I tried to reach out on their help function but get the same message over and over. There is no way to contact them directly and is this totally unacceptable as they only give you 48 hours to query a delivery. This needs to be investigated as this is not acceptable and will not be using Ubereats again if this is the kind of services they deliver.
