Shiprocket: eCommerce Shipping

I have been using this platform for a while and was happy with it but lately it their service is POOR. I tried their advanced paid plan for a month for international payments but it was never activated on my platform. I only came to know on the last day that they needed some paper work. When I tried to downgrade the plan it has not been done and now I will be charged for another billing cycle. :((( A account manager would be a good idea for each client.
