Bad Customer service with no assistence

A telkom representative came to my workplace and offered a contract. 10MB line with 50gig data<br> After some time i realized that the contract doesn't suit me. It is expensive and i i keep running out of data.<br> I requested at the telkom store to modify the contract to my needs and im always told to contact the telkom call centre 10210. however it does'nt ever work. If it does work, i hold on for long periods of time before the call cuts.<br> I need to modify the contract to a slower speed with an uncapped facility to a range of around R350 per month. If telkom cant do this, im willing cancel the contract early and move over to another service provider who is willing to provide customer assistance as telkom clearly doesn't assist customers.<br> <br>
