I had ordered one red top from the online shopping app and the size was bigger for me so requested an exchange of the product. On this, the delivery boy has picked up product from me within 2 days and he said that the product is still with him and sbl has not picked up that and i have not received my product yet, i wrote them a mail on this 3 times with 3 reminders but no response from them. I'm highly disappointed with this.
I tried gto call them on their contact but they have stopped it as well.
Order no: #[protected]Red fawn off-shoulder top).
