BIG Bazaar - Tremendous Delay in Delivery of Product

On Aug. 13, I had visited Big Bazaar in Chennai and bought some furniture to the order of Rs. 12000. It contained the following items: two book Paolo shelves, a micro stand, and two side tables in light brown shade. On 17th Aug, I got a call from Mr. Girish (09884655406) saying that there was no stock of the book shelves in the color that I had ordered, rather they were in a different lighter shade. He asked me if I would be interested in the lighter shade, and I said yes. However, the delivery will not take place on 17th, but on the 20th Aug. On that day, the delivery people show up around 8pm, with book shelves in the wrong shade, with the wrong shade for the two side tables also, and a micro stand that was defective. After talking with Mr. Girish, he confirmed that he would send the correct items on Monday before 8am. This was arranged after I explained him that I will be traveling on 22nd, and so won't be available later in the day. However, on 22nd morning no one showed up. After waiting for weeks, and trying to get into touch with Big Bazaar, I still could not get my items. Finally on 3rd Sept, almost a month later, the delivery people show up at 10:30 in the night. I mean what time of delivery is this, that too without informing the customer, whereas Mr. Girish had said he would confirm before sending the items. Despite all this delay, the book shelves were still not there, and the micro stand piece was still defective, and so the complete order was sent back for replacement. After talking to Mr. Girish again, we got the verbal consent that the items will be delivered in the coming week. So far we have not received any items, and no confirmation from Mr. Girish. This is terrible service from Big Bazaar. They simply cannot confirm a delivery, get the right items, and cause distress to their customers by sending items at odd delivery hours, not to mention the immense waste of time and effort of the customer. I want my items on an immediate basis! I have waited enough! Please take some immediate action in this regard.
