RECIEVED THE WRONG ORDER

Homechoice agent called me last week about the 4.3l Air Fryer that is on sale, so I decided to place the order after 4 days the order arrived at Groblersdal Clicks. So I collected it only to find out that they sent the wrong order instead of sending the 4.3l Air Fryer, they sent the 3.5l Air Fryer so I sent them the email they gave me the reference return number so I returned the Parcel where I picked it off... then few days later they sent me an email saying I should pick it up at Groblersdal Clicks and send it to the nearest showroom because they are not going to collect it there. When I ask about the showroom they don't provide me with one, when I search they showing me showrooms which are at another provinces how am I supposed to get there coming from Limpopo to somewhere I haven't been there? Whereas they allowed me to leave the parcel there at the first place, before I left we called them and said indeed I should leave it there they will arrange with the courier guy but when I call them now they busy dropping my calls, another lady was willing to help saying they will collect that parcel but after few minutes later she changed her mind and dropped my call... they even telling me that they going to bill my account on that order which I no longer have, which they instructed me to return it at Clicks in the first place , on top of that they charging me the amount of 4.3l Air Fryer whereas they sent the 3.5l Air Fryer. Am telling them that it's impossible for me to collect that Air Fryer because am not around Groblersdal until March they keep on dropping my calls. When you order they don't take time to deliver but when it's time to return that order they give you different stories.
