Line downgrade without customer consent

Hi,<br> <br> Good day. Last year I installed Telkom simple uncapped line and everything was fine until last year December magically my line was downgraded to Telkom Simple with a 20 GB soft cap. I phoned 10210 and a complaint was logged. I received a reference number, I have phone them many times since, but I haven't received any help from them. I phoned them again this morning, 6/15/2015 and was transferred to the sales team where after waiting for around 30 minutes I hung up. This is ridiculous. How can a line be downgraded without the consent of the owner. This is *******. I am not receiving any help from the call centre. Please someone help me. I don't know what to do.<br> <br> Regards,<br> <br> Friggin frustrated Telkom customer.
