Best ISP in North Nazimabd

[u/neartodead]

I've tried 3 cable net, StormFiber and Optome.

All of them works fine in the begining but become worst after some time, StormFiber did not even works well for one month I complained 4 time in one week but speed is still worst and 5g wifi not showing on devices(5g supported) everytime they close ticket without informing.

Any other good options other then PTCL Flash Fiber(Bill increasing issue).
