Customer Service Non Existent, I had to do YOUR JOB!

The customer service I receive last night was appalling. He couldn't even do his job and then the driver who delivered my food gets in trouble because customer service cant do a simple task, change an address or call a customer back. So I asked a manager to call me back to discuss the serious lack of service, and I am still waiting!

This is appalling, I almost want to send you a bill for doing the work of someone you actually employ to do a job. I had to call my driver and organised delivery after I had done my duty of calling 1 minute after placing an order when I realized there was a mistake on my order. So I called and asked to change the mistake. I was told that everything was sorted and the driver was contacted.

I notice on track my driver that he after collecting my meal and being told the address had been changed that it hasn't been changed. So I call your customer service back and the same rep tells me, "oh we can't change the address." so when my number is on the order he can't bother to call me back to I c an either cancel or change my order!!

What is the point of having service if no one provides it! And I know about customer service because I run an entire team of customer service reps, so please explain to me what your reps actually do? because clearly basic service doesn't exist.
