MTN ARE ***** AND THEIEVES

MTN is a bunch of rougues. I took out a cellphone contract and a router contract with them. They have been charging me R100 over my stipulated amounts. When I queried it they are saying it's VAT. What ******* is that? When you take out a contract and agree on the amount they are not supposed to change that amount. Plus even the router contract i took out was not what I agreed apon. Again they lie and say they I did. The router I am still paying for barely worked 6months. And is now not working because they sold me JUNK. MTN yourl are the worst.
