Samsung — Cant get my product from service center which was in under warranty.

I am from godhra gujarat. My jobsheet no is [protected]. I submit my A70 phone last month for display comnbo problem in under warranty of 3 months. I check my status on whatsapp on 6th oct 2021 and its shows product has been completed. When i visit samsung service center then they replied me that we cant get any payment approval from upper side so we cant provide you your ready product. Then i complaint in customer carw on 8th oct 2021 and they replied me that wait for 24 hours you get your handset. Am again wait and visit samsung care 10th oct 2021 but same replied from there side and again am connect on customer care and they replied me again for 24 hours. Like this all time they replied me same ans on 11th 12th 13th oct 2021 also. I have evidence also like phone call recording whatsapp chat with samsung support. Worst service i have seen ever.
