Hi I placed some orders in big basket
I paid my payment but it said your payment is declined so it is moved to cash on delivery. But from my bank account the amount was reduced
So I raised a ticket. They said the server was down so payment details was not updated. After that also it was in COD . So I just cancelled my orders. They said amount ll be refund within 7 days. I don't get till now. When ever I tried to call their customer care number it says like you r not allowed to call this number and I sent a chat they says only hi how may I assist u. After that no words from them . Really cheater.
