Worst customer experience

I ordered a new dstv package online. A few days later I received a call where they took my details and said someone would call me back within 24 hours to arrange an installation. 2 weeks went by so I decided to contact the call center. They also took my details, apologised and promised that the matter was escalated and someone will call me within 24 hours. It has been been more than a week since I made that call. Today I called the call center again and spoke to the lady named Hlela who rudely hanged up in the middle of the call. I have been their loyal customer for years and I'm truly disgusted at the way that they are thanking me.
