raising complaints with consumer care at [protected],
emails to [protected]@afbri.adityabirla.com since Oct 4, 20, standard reply that its being looked into,
the portal shows delivered whereas the items were missing in shipment. A second order no 3767186 also had 1 item still undeliverd.
on speaking to customer care they insist that all items have been delivered and accepted by me in person.
i want a formal apology, a total refund for items not recieved and compensation for harrasment and time lost in chasing my orders.
