My latest love letter to M1 on its fan page

My home M1 fiber network is currently down.
After the technician instructed me to do this and that over the phone, she said the Huawei router was faulty. However, the Huawei router was OUT OF STOCK.
She suggested that I could switch to my own router while I could connect my home telephone line to the modem instead of the Huawei router. BUT, activating this would take 3-5 days.
When I questioned how long would the new batch of Huawei router be available, the lady told me she didn’t know.
What am I supposed to do now? Just continue to pay the monthly bill for the disconnected connection and such service while waiting for the new router?
1. Is Huawei router so lousy that it has issues frequently, such that many customers’ routers have to be replaced and thus M1 has, sadly, run out of stock?
2. Does running out of stock for the Huawei router means new M1 subscribers cannot sign up currently as well?
3. IF new subscribers are able to get their Huawei routers, does that mean that M1 values only new subscribers while it ignores existing ones since they are already contracted?
If this issue is not resolved ASAP, I would be seeking advices from IDA, CASE and all popular forums that Singaporeans are using. I would also have discussion with my family over the 4 existing M1 mobile phone plans.
I thank you in advance for replying to me.
