RAIN POOR CONNECTIVITY

I have have been using RAIN since the lockdown and the service has been satisfactory except since the past days , I have been without internet connectivity for the past 3 days even though they have deducted their monthly subscription from my account .I have been attempting to contact them on the following number and to no avail as the phone becomes disconnected .As a result i am behind with my deadlines and my work , this has become frustrating .
