Telkom frustration!!!

Telkom called mo to offer an upgrade from my 2MB to a 10MB line which I accepted. Nothing happened because apparently the sales lady didn't do her job properly.<br> I then app**** for 10MB which was activated in November 2015. I have been paying for the xtra speed since November, but my data speed actaully went lower.<br> I have had endless frustration dealing with support and them passing the buck between sales and technical. On 3 occasions they hung up on me when asking for a supervisor.<br> <br> I do not know what to do to get this resolved!!
