5 Mbit upload speed on 1Gbit pack

Hello,

For the last year I have been consistently  getting slow upload speeds of 2-9 Mbit/s during working hours. I was on the M200 pack so have upgraded to 1Gbit in the hope I would get faster average speeds. However, I am still only getting 5 Mbit. A recent engineer visit got cancelled because apparently there was a fault in the area. The telephone support keeps saying "oh it will all run normal again after this is fixed" but the issue has been around for the last year. Upload speeds ar usually between 500 and 700 Mbits/s (1 Gbit in the early mornings).

The speed readings are taken using the built in SamKnows Real Speed SDK so are better than "wired".

Below are my details:
