Why Zerodha is better than upstox?

I am looking for another broking platform as the current Upstox has technical issue and they are either not interested to understand technical limitation of their web platform or not interested to invest or address the customer's issue. When under same circumstance (hardware, software & connectivity/ configuration), other broking web platform work properly without any disconnection & reconnection issue during the laptop usage (not idle even for a second), why Upstox disconnects & reconnects automatically? And, then they ask the customer to do profile change of chrome, uninstall antivirus (when antivirus is not at all installed on the machine), get telnet data/ config from the ISP. Is this what a vendor like upstox ask their customer to provide when they are earning from the customer and the responsibility of giving service to the customer lies on them? Poor tech. team & support/ customer service. In the world of software product delivery & service, it is the responsibility of software service provider to analyze the issue, find root cause and apply fix to their codebase and not fool the customer using their platform.
