I have ordered fresh "blooming insight - rose flowers", a greeting card and big cadbury celebrations pack for my wife on her birthday (12-aug-20). I have ordered 2 days in advance and i got confirmation too from winni.
The delivery time would be 10 am - 9pm and i said ok.
On 12-aug-20, the delivery message was not done till 5 pm in the evening. I followed then using chat option several times regarding the delivery and they said we will deliver it on time.
I received my order and to my surprise, they have arranged everything with the local vendor at the last minute. I have received low quality different product instead of the ordered one.
I have ordered fresh roses (10 pcs) and they delivered only 6 which is already dead roses
I have ordered greeting card and they delivered 10 rps card
I have ordered cadbury celebrations pack, but they sent 3 daily milk chocolates worth of 80 rps in a plastic cover. Even it was not packed.
I have paid 1323 rps including delivery and what they deliver is for 300 rps. I have reported this to winni customer care and what they offer is 100 rps refund also they said that the location is remote thats why they could not arrange properly. I have checked with them before ordering and they said yes. Also the customer representative said that we will send these kind of shipment to the remote location and what sort of attitude is this?
Totally ruined the occasion and dont beleive in them. They are not fit to run this business very worst. This is my first time order to them and i have experienced this.
Can anyone suggest me how can i lodge an complaint against them, since they are looting our hard earned money.
My suggestion we can deliver whatever we can but do not beleive in these people anymore.
Whether kanchipuram is a remote location, if yes then they should not have this option for delivery.
