Bridge2business.in/ — After payment done they are not work for account management

I had received 4-5 calls from b2b as daily before payment done and they told me they provide me best services for account management and remove all complain which i received my amazon seller account but they canot do anythink what they say.

i have paid 4500 for 1 month account management service but after 20 days they have nothing to do on my account, they just do answer of complain which i received on my account, i have not paid money for this.
