poor service

I upgraded to a 500 rand package that is top up but im constantly having problems with my number being offline and my bill is always different and now im suppose to pay only 500 rand a month but my bill is now over 1000 and the lady named jane now tells me over the phone we signed a \open contract"which we never agreed upon and now she claims she cannot do anything about it <br> Autopage has really poor service and my mother and i have been loyal customers for a number of years <br> This is unacceptable and ********* <br> Every month i have issues with my invoice or the connection of my mobile services <br> The sales pitch and the binding contract differs from each other they tell us its a top up contract but we signed for an open contract <br> Very unhappy about this"""
