Stuck in the M-Spiderweb of useless providers and customer service!

I logged to upgrade my line speed on fibre on the 26th April is still not done and not one useless agent is able to do anything. I have logged queries on the APP and still nothing. Avoid MWEB, I am now trying to cancel and cannot get anyone to action anything. I need a faster speed and need to move to another provider but trying to get anything done by MWEB is beyond impossible. As I write I am number 33 in the queue and guarantee again that this will be a waste of time. Does anyone have any advise?
