Address:	Bangalore, Karnataka, 400025

I have ordered an ac through flipkart with order no:order id - od[protected]
Product - hitachi 1.2 tons 5 star split ac copper

I have received the above mentioned product a week ago. The same was notified to flipkart the same date. Since then we don't have any update on the availability of the technician. Every time we ask we receive a mail saying that the issue is escalated to concerned team and requires 2 days time to resolve. Please note that without updating the delivery of item into ur database, flipkart is bluffing the customers. Pls note that if flipkart intends to have long term business, customer relationships is quite necessary.
As i couldn't attach invoice, pls consider this as a matter o[censored]rgency and sort out my issue.
Attached is the invoice for the same
