Not sure you are going to get a fast fix.
I'm in the KT4 area and have been waiting for the same fix before Feb 2021.
As you can see from this post the fix dates for F008611099 so far have been 26th Feb, 10th March, 24th March, April 6th, April 12th, April 27th, May 11th, May 25th, June 8th and June 22nd.
I suffer the same problems as you with slow upload speeds during work hours.
