I used to oversee WAN and peering operations for a large multi site. Residential ISPs almost never respond to reports of inefficient routes unless you are one of their peers, big business customers, or you really know your stuff and send in a detailed report showing asymetric routes, bad bgp info, etc.
As far as a VPN goes, that probably wouldn't help either. You will probably increase the number of hops and latency. Your route will still egress your isp gateway, to your VPN provider, then travel over the Internet and to your remote server, while adding additional protocol overhead. Yes, it is remotely possible that there is an improved link from his regional VPN node to his remote provider, but unlikely from my experience with traffic engineering.
Actually in my case it did help. I got faster speed to one of my VPS in Paris (OVH) if I use VPN to Singapore first. Heck, even my VPS in Singapore (also OVH) is faster too after connecting to the VPN. My ISP probably really have a bad peering with OVH.
That's interesting. Any chance your ISP could have been qos'ing streaming video? Although Singapore would be about the one place where a VPN concentrator would help; it is pretty much the big fiber hub in that local region for East, West, North connectivity.

I don't think they have QoS beyond enforcing soft data cap at 2TB. Another weird thing I notice with this ISP is how bad sites hosted behind cloudflare would perform. It usually fine, but sometimes they have random high latency on random assets (js, css or image files), and when it happens the speed to that site would tank too to just a few hundred KB/s or less. When it happens it'll magically gone by using a VPN.
Oh man, fucking tell me about it. I remember Verizon support gave the absolute runaround when I was trying to debug why my server was absolute garbage in San Jose vs LA. Took me 3 separate support calls for them to finally do something about it. It also took me a while to figure out it was an ISP issue in the first place.
