They are at it again! I response yet again!

I posted a review a couple of weeks ago and they still have not provided a response, I have sent a few emails within the last few weeks and again no response! The service is ridiculously frustrating and terrible. Please think twice before joining them. They have told me that I have a clawback fee I need to pay when I requested t&cs they did not provide this as this was not initially in the t&cs when I joined! I closed the service after being debited incorrect amounts, when I called to try and resolve this I received no response and barely any assistance other than being told billing was going to resolve, they come back to me a year later after closing the account and paying the 3k about clawback and I called and confirmed if it was paid the agent told me yes, a year later I get a call and they tell me I still owe the claw back. Further they send me an sms noting they have handed me over to debt collectors without due process and no means of resolution on thier end, sent emails trying to enquire about this and guess what still no response. I am escalating my query to ICASA. I am sick and tired of the stress caused to me by this provider in addition to them originally and incorrectly charging me for two devices they do not care about your hard earned money and providing at the very least decent customer service to try and resolve your issue that they created. Think twice before signing up with them please!
