Speeds for technician day only

Hi, the day your technician came in the speed seemed to be fine throughout the day, now I am experiencing terrible speeds I'm on the 100mbps package I can't experiencing so low speeds I will attach to this email the speeds, please help I can't be constantly asking to solve this issue with you guys on the you guys come in the speed is always fine as soon as you leave the speed starts to drop pathetically as I previously stayed I don't expect 100mbps exact but low speeds that I am getting is not adequate, furthermore the I am having buffering issues on places like Amazon prime, YouTube premium, Netflix, these are standard streaming services and the video can stop suddenly and not load back up or the video quality becomes poor, so yes I am not being harsh know rude or unfair but the service quality is completely dipping and poor I expect some sort of consistency, again please find attached speed tests.

Tell me that the below is fair for the package line I'm on, it's not and this is me being completely bearing I literally did these speed tests next to the router, on the previous visit which is the 4th time a technician came to my home I the speed was averaging 75mbps and strangely the speed is always fine when you guys are popping in to test the next day it's starts dipping until it becomes irritating and unbearable please you guys need to check what is really the problem I don't even live In a big space to experiencing reception problems and dips in speed, even my TV that's next to the router has freezing on YouTube, fibre is a asymmetrical service, with no ratios involved there should be no throttling I hope that's not what is happening cause evidence seems to be that way, It's normal that on 4 occasions that you guys visit and the speed is fine for that day and then starts to drop again, I await your response.

I have tried to get help and feedback from your app multiple times but to know avail it feels as a customer I have to beg for what I am due
