Bad Service from Nkululeko from Mr Price Mobile

I received a phone call from a guy named Nkululeko today @ 10:16. He wanted to notify me about a special they as Mr Price Mobile are currently having of some tablet with some amount of data per month (couldn't really understand as he was not clear and speaking so fast). Firstly, he didn't even bother to ask me whether it was a convenient time to talk to me, he just jumped into his sales pitch, not even asking how I was. Secondly, upon me informing him that I wouldn't be interested in anything like that, he just hung up. No \thank you for your time"or any telephone etiquette"
