I order for a new i phone 4 S phone but E BAY delivered me a used and old product .I informed the e bay customer care many times.but different executives are giving different reasons every time .In the month of November I paid full cash for the product but even today I not received my money.

They told me that as per their company policy they sent a reverse shipping tag and I returned the product through fedex. Now already closed to months over but still now I not received my amount.

Please help me to get my amount.
