What do I do when a Seller refuses to release goods after I have received debit alert?

The Seller can dial *402*1*Sellercode# to get a list of his/her last 5 successful transaction or *402*1*Sellercode*Transaction Ref# to confirm a specific transaction. The Payer can also report to his/her Bank and refund will be made in 24hrs after confirmation that transaction was successful.
