Herotel Empty Promises

Got Herotel 2021-09-28 (+-). Started off fine, I pay 499 for 50Mbps fibre (thats MEGABITS!!! NOT BYTES) Dont be fooled, Herotel promised "not throttled", went fine for about 4 months now I dont even get 10 MegBits per second... POOR POOR service. It's not even 1 megabyte per second!!!!!!! Come on HEROTEL!! I LEFT RAIN FOR THIS ****...
