Alliance — Regarding slow speed after upgrading the internet line also

Hi, I am facing slow internet many times but I did not complaint but this minty I faced a lot.so..the thing is I do recharge starter pack but when I use zoom or downloading some files it gives very slow speed like 10-20 all and average that also after 5-6 pings.thats actually hampering my work. I need the permanent solution otherwise I have to think about alternative. The think I don't that much speed based on my package
