How Do I upgrade my internet speeds?

any1 here know how I can upgrade my internet? I called my internet service provider multiple times this year asking if I can get better speeds in my area... I have 25 down and 5 up now for like 3 years, so I cant rly stream on twitch or I dont get the speeds I want., In april I called them and they said I will get better speeds "very soon" and its been like 6 months, I also get higher ping when other people use the internet and stuff so its kinda important for me, they said I cant get higher speeds unless the line to my house gets upgraded, I live in the west of Ireland and a lot of people around me have faster speeds than me like 150 down and 30 up , which would be perfect for me. can anyone help me?

If this is genuine, rather than pre-spam advice is as follows

Core expertise of this site is UK based, so provider specifics will be generic for other countries.

The key part is that your current provider will be under no obligation to tell you about alternate providers that can go faster, so you need to find out who the ISP of this 150 service and whether they can supply to you and at what cost.

You can stream to Twitch with 5Mbits upload, just set your resolution to 720p @30 fps and use 3,000Kbits (3Mbps) most streamers use 720p to allow for more viewers.

Twitch has a nice page with these settings here: https://stream.twitch.tv/encoding/
