Myntra.com — extension of delivery date

I have placed my order on the 29th december 2017. I still have not received my orders. I received sms on 30th december 2017 itself that my orders have been shipped. The stated delivery date by myntra is on 6th january 2018. But i have received an sms stating that the delivery date has been extended to 8th january 2018. This extention of delivery date is causing me inconvenience. I kindly request the myntra team to please consider this and do the needful..

Thanking you
