No Response from Vodacom on last complaint

And still nobody contacted me from VODACOM. There is another e statement in my mail box for the Top Up contract that I had with them.<br> For how many months do I still have to pay for a service that I am not using? Will I be refunded with bank charges and interest?<br> Years ago my experience with one complaint was much more efficiently dealt with. This is a big disappointment for me but VODACOM suppliers are still contacting me to sell me another contract?
