2 years of incorrect billing

Saying that I am disgusted is putting it lightly. I have been charged for 2 years for something that I requested to be cancelled in July 2013. I lodged a complaint on 13 August 2015 and was told that it is their fault and that I would be refunded. 3 Weeks later,numerous emails and numerous phone calls later, I have not been refunded and the component is still active. I have been billed again on 01 September for it yet again. I am at my wits end dealing with these *********** fools and today was the final straw when my wife was told that they are doing us a favor. I have never dealt with more ***********, arrogant, unprofessional and insincere people in my life. This is appalling and I am seriously questioning why I have been loyal to these fools for more than 15 years. Time for me to look elsewhere :-(
