Looking at your line stats the connection is holding at a low SNR 5db on the down so the sync presently is ok. However if a fluctuation occurred there is more chance that the line will drop and speed reduce. You could request the profile to be increased this may stop drops but would also equally reduce the speed.
I would check what SNR profile you are on to see if it is holding as expected. 5 on a 6db profile or 5 on a 12db profile.
I would ensure your local diagnostics are done, PSTN line clear of noise, connect to the test socket, change filter, RJ11 cable, alt router to make sure it is not anything local causing the issue.
Afterwards I would suggest seeing if there is a pattern to any line drops and how many drop there are. Ask your ISP to look at the graphical RRT data on the line if they have access to do so. They hopefully will have access to see a daily breakdown on the amount of SNR fluctuations, MTBE, initialisations etc. The main one being the SNR to see if it is spiking, this will cause the sync speed to change and you may need to progress it as an intermittent fault.
If getting nowhere then look to escalate the fault but always be nice to technical staff and be willing to follow the procedures.
