Bad Service

Hello. Phoned Customer service and requested a call back explaining I had 1 minute remaining. I waited for a bit the called back. Spoke to a rude gentleman by the name of Cyril. He rudely told me I told him I had 1 minute remaining but I spoke for 2 minutes. I had obviously put in more airtime while waiting for a call back. When they want business then 5 people will call you on the same day. Why have a call back system when you don't want to return call.
