services rendered was poor

Today a friend and I went to the Mugg & Bean at Cape Town International at the departure terminal on 3rd floor. it took them 20 minutes for them to deliver my order ( cheese cake and coffee). When the order finally arrived my coffee was cold and the waiter did not even appologise for the delay. I had to wait again for a waiter up to 15 minutes just to request a refill on my cup , the coffee only arrived after 10 minutes again no concern is show for the delay in delivery of services. we requested to speak to the supervisor on duty, to my surprise she kept walking up and down pass us and did not even bother to attend to us. after 1h15min of poor services we requested the bill, which was a process also as apparently we were not allocated a waiter on the system. the bill also took its own time as we had to wait for the supervisor to come and overide the system. I am very dissappointed at the level of service that i received from your company today, I doubt I will ever go eat there.
