Vodacom not delivering the fiber speed they should

I have installed Fiber at my house in Feb 2021, Since I have Upgraded my line from a 10m to a 30m line, For almost 3 months now I have been on the phone with them I do not know how many times already, I have opened service ticket after service ticket and Vodacom simply does nothing but close the ticket and tells me it should be right, if not I should send screenshots, I have sent about 7 sets of screenshots of the speed via Lan Cable, WIFI , and Today I get another mail that it should be restored, yet again nothing, Just asking again for screenshots (Did send again).
