Poor service No feedback

This is not the first complaint about Vodacom. A lady phoned last year as I asked for help to get the Vodacom account less than the amount I am paying. She suggested a router and explained how it will benefit me. Then I received two routers in the mail and the account .... I am paying more than R200 more now. Vodacom in Sasolburg said they cannot help as telesales and Vodacom are two different companies. This is a few months now that I am trying to fix this problem, but no luck. Vodacom is quiet and the debit order goes through every month. The customer is just another number for this company! More than a year ago I asked for help as we rarely have a signal where we live. Vodacom is quiet. At first they promised an antennae, but we still struggle. Sometimes we do not get a signal for a whole day. The cellphone is also our only means of communication. POOR service! This is a complaint for the ACCOUNT due to an extra router which I do not use and the POOR SIGNAL
