Mobile Number[protected]. My Order is suppose to delivered on 15/1/2020. But when i try to check the status this site is not opening, this mobile number is also not working.
When I search in Google i got "Antgirlcollection.com Consumer Helpline No. [protected] Kolkata No. I got IVR message all customer care executive busy on other calls. I cut my call, immediately i got call from [protected] the person told me that their site is facing some issue and under maintenance, he checked my details and told me that your order has been cancelled and you will immediately get your money refund through google pay or phone pay . He asked me google pay number and how many bank account is added in google pay. I told him to return money to my credit card account only then he told me to download some easy pay from play store immediately while call is ongoing. I said very rudly that if you don't listen to me you will get your payment in 4 month in your credit card account. I asked him if i want my payment back immediately the what i have to do. He said download the app now and he hold the line. I feel something fishy so said my mobile battery is down i will call you back on your customer helpline number after some time.
How i can get my money refund through Razorpay.
Please Help Me.
