Bad services

On the 20th of March 2021, I have upgraded from100Mbps to 1Gbps, and right from the beginning, I struggle to get the speed that I have paid for they always blame the other party but nothing gets done for the other party to fix the situation when it comes to payment they are very fast to take your money but when there's a problem you don't get discount for a service that I am paying for, it is now eight days later and nothing is done, for me to cancel this upgrade I must wait until the 22 of the next month to revert back or cancel this service. I want action, not excuses.
