Address: New Delhi, Delhi

I've submit my iphone6s at apple authorized service station "b2x service solutions india pvt. Ltd. Nsp wazir pur delhi 34 vide job no. Dpp[protected] on 4th aug17 (11.30 a. M) but unfortunately expiring 10th aug 17, 6.00 p. M i've not received any call/feedback from them. I requested to standby phone but the mr. Himanshu of apple service center rudely behave and deny to give any stand by phone. How much time required to service or feedback and this set in warranty period and hardly use phone. I've doubt the quality of apple phone also.
