Paying for returned goods

I ordered items online and the goods delivered were partially incorrect. I returned the wrong goods, sent multiple e-mails and made calls to find out why my instalment has not yet been adjusted with no avail.<br> I`m always being told that someone will come to me or that the returned items are incomplete therefore they can`t help me. Yet there is no suggestion to at least return those goods to me so that I at least pay for something I have or refund me for my made payments.<br> The call-centre agents are *********** and clueless with no basic professional writing or communication skills.<br> This is the worst service ever, whereby people are told that the return procedure is convenient and efficient, knowing very well that once you receive a delivery you`re stuck with it along with the payment!!!
