Dg Shipping — Payment issues

I have made a payment of rs 300 on dg shipping website on 4th oct 2023 for my bsid appointment . but until now I am unable to book an appointment as the site keeps restricting to book an appointment saying to make payment before booking an appointment. I complained about this to respective mmd and they asked to wait for 5 days from the date of payment. Now my problem is its already more than 7 days and still I couldnt make an appointment. Everything about dg shipping is delays and irresponsive. even after money is deducted you wont be able to do anything .

my details

bsid application num - 328770

payment date and bank - icici bank on 4th oct 2023

indos num - 23ZN7143

Please help me with this issue I am stuck for no reason.
