I have big update. I pursued my case through
pgportal. After logging the complaint, I received a call from someone in national headquarters next day.
Complaint date 22/04/2020 and today I received the vouchers. So resolution within a week including weekend. The issue was confirmed with resolution on 27th and promised a resolution in 48hrs and they fulfilled. I have also discussed 1/10th upload speed. He is clueless about this and asked me to log it through pgportal so that this can be taken up at highest level and resolved.
He also told me the voucher issue was present for few other users and this was resolved for them as well.
