Den Networks — current plan is no more available

I am using den broadband from 2 years now. We had issues of network but we ignored at times as we are working and used wifi only 5-6 hrs while a home per day. But now in the month of march my plan of 393 inr was due to renew. When i went to recharge my account i did not find same plan on 24 mar and other option of higher value was there to which i called there person and got to know they dnt have same plan anymore and have to pay more now. So these guys have started taking advantage of the situation of covid 19 as they know people can't get new connection for lockdown period and they can take advantage of the situation and increased the prices.
I now can't use wifi which is now coating me double the value of month which i dnt want to spend
I want them to offer me my same plan as soon as possible
