Paid for a Honda PArt

Hi <br> <br> My name is Ignatious Pasala, I have bought a part from Honda Midrand and when i went to technician,And they said that is a wrong part for the car. Then immediately i went back to Honda midrand and requested to take it back because that part is a wrong one that i ordered and they don't want to take it back, so i end up with loss of R 2600 there.<br> And secondly i ordered Motor Fan and I paid the whole amount on 31/01/2015. Initially they said it will take plus minus 10 days from overeseas.<br> But still now they didnt get that from overseas and now they are giving excuses saying the part will only come on 25th of march2015.<br> But when i asked them last time 2 weeks ago to refund that amount so that i can get that part from one of the place i know. BUt they said they cant and now i want to use the 1st motor and this fan where it goes together. But they said they cant return or i have to wait upto that time to come the part from Japan. <br> Kindly advise me here.
