Alliance — no alliance connection since amphan

Address:

1/1 Lake Avenue Prashanti Building Flat 24 Kolkata 700026

No alliance connection since amphan. Getting no response from local alliance as they are no longer picking up my call. I have to work from home and it is becoming a pain to work without a stable internet connection. Getting frustrated with the lack of response and not being provided any eta for internet restoration. It has now become over 2 weeks after the storm.
