Rude telephone call trying to sell me a phone and putting the phone down on me

I have received SMSs encouraging me to look at a new device. I went to the store at Cresta to enquire about it. A very helpful pointed out that if got one before the end of my current contract, I would be paying for two which doesn't interest me at all. A young woman from Red G called me at 09:54 and I told her I understood how it works and that I am not interested in this ******* offers. I told she could email me if she wanted and I would analyse it there. She then put the phone down on me!! Thanks to this rude behaviour I have started looking at other service providers once my contract is up. I had never done that before but thanks for getting me to shop more carefully rude lady.
