Overcharge and poor product knowledge

I signed up for wifi router which costs 150 per month. They kept billing me 400+, I called customer care to limit it, they said they can put it to R50 I should go to the store to make it zero. To my surprise following month im billed 600+ after being assisted at the store to limit to 0. I call again they log stupid cases which are never reolved or responded to. Customer care confirms in may that limit for june will be put to 0.01 as it can not be put to 0 because it automatically makes it R500.(information that both the lady from customer care and the store did not know). As per case number ********** 0 limit put to 1.00 and end January 700+ is deducted from my account. A lady names nontsikelelo tshabalala from customer care informs me that the person who created my contract did not complete it, he did not put the IMEI number( probably because he was busy trying to charm me and asking inappropriate things) that is why he didnt do his job properly and why my limit cannot be changed. I suspended my account in order for me not to use it and to see how much billing will I get. I STILL GOT BILLED MORE THAN 150. So I reversed the amounts. Only after then they started Billing 150 as per statement, im still waiting for the cases to be resolved and they keep taking 2000+ now.

I have sent so many emails and called many times they have poor knowledge about their products. They do not care and not once did I received a call as im told at the store. Im sick and tired guys. This is poor service man.
