Rain pls wake up! You need to do customer support properly

No internet access from early this morning. Acrually this is not first time. I turned router power off and on many times and nothing changed. I have SIM only service as well for back up and this is working which means network is fine but something wrong with router.

I logged the fault and they rep**** " pls turn off and on again " they think client is stupid and don't think ?

And I requested to replace router but no reply so far.

Rain, pls wake up !! This is not proper customer support
