Useless customer service agen

I ordered 2 tracksuits and the pants of one of them is too small. As explained numerous times to the agent, Nolwazi, i dont want a refune, merely and exchange, and the link that she keeps sending gives me the same error as on the website and I am unable to process the exchange. I have been tell Nolwazi this since Monda, it is not Thursday and she has stopped responding. She kept asking whether I would like a voucher or chse refund and I keep telling her that i want and EXCHANGE ONLY. The she send me the same link OMG i am not sure what is wrong with her but for this whole week she is not getting what I am trying to say!!! SOOO FRUSTRATING!! I have asked if someone else is avail to speak to but of course no response on that either. Well done Planet54 i will never order from you again. As a first time customer, never aagain and I will warn others not to purchase from you either.
