Welcome to the RSAWEB circus - Poor fibre network performance. Lack of proper service and invoicing errors

So I submitted multiple tickets for poor performance and periodic drops, which RSAWEB could not remedy. We agreed to alter the package from 120/60 to 60/60 to see if this would result in more reliable performance. RSAWEB confirmed the above at the new monthly fee, but the line speed remained 120/60 despite being advised twice that the package had been changed to 60/60. The invoicing also changed to a higher inaccurate pricing, but the line speed did not change, as I was still able to validate with Ookla speedtest and received 120/60 and still with plenty random drops and lag. Unfortunately, they will probably respond with a boilerplate response and have no idea what is going on.
