No response or reply

I've tried calling the telkom 10213 call centre numerous times to apply for a contract. I've held on for periods of upto 20 minutes, with no reply. I've also app**** online, but there has been no response. I've even filled out the 'call me back' form & haven't received a call back. All of these are listed as options for customers to apply. Infact they are advetised & promoted in the Telkom promotions booklet. I can't understand why a company would spend so much on advertising & then make it impossible for ready & willing customers to apply! <br> Could someone kindly get in touch & assist.<br> Thank you
