Apple India — Billing Issue - GST

I bought an iPhone 14 plus from iplanet Jayanagar on Valentine’s Day. I asked for a GST invoice and received the same. The GST invoice has not been uploaded on GST portal for me to claim ITC. I sent an email to iplanet store, sent a WhatsApp as stated in the invoice. The email comes back stating trying to deliver for 4 days, the store states write to customer care. WhatsApp has no response. How do you contact them? Does iplanet pay gst
