Trade India — Not responding after payment

The employees of Trade india used to call me 3-4 times in a day for becoming a member of this B2B portal. After payment, no steps have been taken for onboarding even after a month. Initially they informed us that onboarding would be done in 4-5days. They also informed us that they will take all data from Indiamart and create a catalogue. Now, they dont respond to our calls, messages.
Astonishing to see such big names in the market indulging in activities like this.
Wondering what they would do after onboarding for business
