Unacceptable service

The restaurant didn't have 1 item, the driver messaged me to tel me to change my order or cancel it and I tried but he didn't change it and said the restaurant cant, I then proceeded to get help from the Uber eats help line and they only said I will be paying for the order as the restaurant is busy with it after I explained what happened and even phoned the restaurant to as what is going on, they wanted to charge me for the whole order and I will not be receiving and food from the restaurant. The restaurant did not notify my that one thing on my order was out of stock

The customer service is unacceptable/unprofessional and very pathetic and now I have to wait for my money to be transferred in 10 days, unacceptable and unprofessional!
