bad customers service

My cousin has an account with dstv but because we live together we decided that I would pay for it. This month I was late in making payment so I only payed yesterday(15.12.05) at the dstv branch in umhlanga. When I left home my dstv was still on so just in case it was later switched off I asked the consultant twice to check for me if the services had been cancelled and if so for her to put them back on and twice I was told ur dstv was still on. I get home my services have been suspended. I call the call centre to switch my services back on they do, but i was then told I short payed by R21.37. Now this has happened to me before. The first time was when I made payments at your smith street Durban and I only found out about it when my services got suspended a few days after payment, called ur call centre and thats when I was told that I short payed. Now history is repeating itself with ur uMhlanga branch. Do ur call centre agent work on a different system to ur branches. How is it that they know more?And how is it that your branch agents can't tell if sevices are suspended or not, and ur total amount owed on ur account. Now I have to waste money fixing something that could be avoided
