Signal degradation

I've been at my current location for 3.5 years and this week the signal took a huge dive. 4G download from 60mbps to 4mbps.

I suspect there's a problem with the cell tower, so my question is can I help speed up a fix by reporting it?

Cell tower: 1479
Location: Mere Lane, Liverpool, England
