IndiTab Esolutions — mobile recharge not successful

I have done mobile recharge for amount rs 1699 for a year bsnl plan. But it was not successful and not received refund even after 2 weeks. My transaction reference number is [protected]igahlgzvk7. Tried reaching them over email multiple times with no proper response or refund. Please let us know the next steps or legal procedure to get the refund at the earliest.

Thanks
