Samsung — Not able to redeem galaxy buds offer after purchasing phone s21 plus

Address: Mumbai

Bought S21plus from offline store on 19th July. Using it daily with Sim. Today is 2nd August and still not able to redeem offer.

Samsung customer care says delete samsung shop app and remove and reinsert Sim and use only on mobile data for 72 hours. I have already done that. Now today on enquiring I get the same reply.

There should be an easier process for redeeming the offer. Many people facing this problem will just give up especially in the current conditions.
