I have emailed the seller a few times to see the progress of my refund but the seller has not responded. I may be jumping ahead of myself in regards to the refund coming back to me this fast. Would like to know the the normal time frame would be.
I bought a product using paypal. received the product and was defective. the seller said he would refund the entire purchase price. i shipped the unit back to him but have got a response back on how the refund will be issued.
