"Nameless manager" Not fit to deal with customers

I ordered 4 meals via Uber eats. The Pedro's Oflaherty road invoices me for 3 meals and sends 3 meals with the Uber driver. I called in at 8 minutes past 6 and the lady who answered says she saw her mistake and will call me back in 10 minutes. 20-30 minutes later 8 try calling the store and my call keeps dropping after every 2nd ring. I then use my wife's phone and I get through the first time around 6:40. I speak to the manager or so he says he is the manager and tells me he knows nothing about the incident, he was very rude and when I asked for his name he tells me "what do you need my name for and what do you want to do with my name". Is this the type of service you train your staff to give your customers, Pedro's? He laughed at me and cut the call. A very bad experience and I don't think I will ever order from that store again. I will make my experience known on all platforms. This is terrible service and your manager is pathetic.
