NEVER AGAIN

I took a fibre deal from one of the door to door sales agents, What i agreed upon was a 20 Mbps upload and download for R710 on a month to month basis last year, I recently found out that my line is a 15 Mbps line and when I emailed them i got no response with regards to the matter where i would like to see the written page where it states what i agreed upon a 15 Mbps line. poor customer service and this is my first and the last time i will be dealing with Vodacom. i honestly had high hope for Vodacom. They just failed me.
