I want to exchange my iPhone 13 128GB and buy an iPhone 15 pro. I have been eyeing the pro models for several years but never bought them. I want to go for the 256GB variant, which costs around 1.45 lacs. HDFC is offering a 6k discount and Apple India's official website is giving trade-in value of 29k for my iPhone 13 which seems a bit on the lower side. Now the dilemma is that I have HDFC Tata Neu with a a credit limit of 1.16 lacs. If I buy from Apple website they will reduce the trade-in value and charge around 1.10 lacs on my card(including the 6000 off) which will go through. I can get a higher price for my iPhone 13 outside but is there any way to increase the credit limit of the HDFC card to make the full purchase from it? Last time I approached the customer care for credit limit enhancement they told to send documents to Chennai.
