Never dealt with customer service as poor as this.

For 9 months now these people has been double charging me for 4mbps uncapped adsl line, I took up a R599 package in November last year and every single month they have been changing me R1158.00 , even during a relocation they failed to install my internet for two month I was unable to use it but still being charged for it. after calling them about 9 times being told to call another department I finally demanded a manager who again told me i need to sort the package deal out with sales, but was helpful enough to dispute a moving charge for me as I was never suppose to be billed for it, however the issue with being double charges is still not dealt with, It appears I am being charged for two lines even though I only have one, I have no clue who this other lines belongs to!!!!!!!!!
