Pathetic service and *********** sales team who enters into contracts without the customers consent

My Woes started with Telkom when in May 2107 my ADSL contract with TELKOM needed to be upgraded. I called through to the contact centre and spoke to a sales person. She advised that there are issues with her system and cannot do the upgrade, but will call me first thing on Monday to resolve and place me onto a new package. This Never happened. I was placed onto an UNCAPPED ADSL LINE and my bill at an amount of R702.63 per month. I called TELKOM on numerous occasions and reported this and I was told that a supervisor will call me. TO DATE NOBODY HAS CALLED TO RECTIFY THIS ISSUE. I AM STILL BEING BILLED FOR AN UNCAPPED PACKAGE. BILLING HAS A REF NUMBER< SALES HAS A REF NUMBER... ALL DO NOT CARE ABOUT THE CUSTOMER. I will not pay a cent for this account since June until my billing is resolved and I am moved onto a package that is affordable for the pathetic service that I am receiving. I pay for a 4mbps line yet I receive 0.23 mbps to 0.96mbps this is totally unacceptable from a company that was to be the best fixed line provider. I have been hearing excuse after excuse from various persons at the contact centre. CUSTOMER SERVICE AT TELKOM IS PATHETIC TO SAY THE LEAST. I need this resolved and my billing to be reversed for the month of June and July and now August. I have open refs which need resolutions.
