I ordered an iPhone 13 128 GB Order: OD[protected] on 22nd September 12:10 AM. I had constantly been tracking my order on EKART Logistics website, when suddenly at 9:30 PM My order was shown to have been returned.
On checking the flipkart app, I found that the order had been cancelled without any notification, sms or mail from Flipkart. After calling customer support I was told the order was cancelled due to technical issues and I asked for the issue to be escalated. After being told no escalation was possible for 10 minutes, it was finally escalated and I was speaking to a lady named Sakra, who informed me my order had been cancelled because of "Bulk Ordering". On enquiring further she told I had placed the order many times, despite actually only placing 1 order, and attempting a second but not going through with it in the morning. Then I was told it was because I was ordering only electronics on flipkart, which did not make sense to me. After no resolution being offered and 39 Minutes wasted I hung up the call.
I received a mail at 10:40 PM informing me about my cancellation finally. In the mail it stated that the order had been cancelled due to High Demand. Every interaction with flipkart gave me a different, vague reason as to why this cancellation happened.
During all this, I was aware that flipkart had increased the price of this device to Rs. 56, 000, an addition of 6K. The customer service rep, Sakra, who I spoke to also advised me to purchase at this higher rate.
In short, I placed an order for 50K, Flipkart increased the price and then cancelled my order, only to ask me to place the order again for 56, 000. Since my refund is also not yet given and will be received only by 26th September, this was very difficult for me.
On speaking to my friends and then checking online, I was made aware that this is a common occurrence in Flipkart, especially during sales. This means that Flipkart is getting a lot of money flowing in through these orders they are not planning on fulfilling, but have access to the capital for multiple days until the refund are finally given out.
Additionally it is highly unethical and predatory pricing because they have essentially forced me to pay 6k extra despite confirming my order and saying it was shipped.
I have placed a new order, since I am in need of the Phone, at the higher price, but a satisfactory resolution for me would be honouring the old price I had paid and refunding me this Extra Rs 6000 charged to me.
The new order number is OD[protected]
