Refund hassles onlincarparts south africa

Stay away from this company!!! on the 1st of July I had purchased a radiator and coil pack for my 2011 vw caddy from onlinecarparts, items were delivered by the 7th which to be honest not the fastest delivery service for a parts supplier! As soon as I received the goods I inspected them to see if the parts were correct and to no surprise the radiator did not match as the images on the website are generic and the descriptions of the parts are vague with no oem numbers to cross reference. After letting them know that the radiator did not match and that I would like to return it, the following day they sent a courier to collect it. They didn't even try to contact me via phone or email to let me know that they were sending someone to collect! On the one hand I was glad that things were moving along but, I also found this to be the first red flag that I was dealing with an unprofessional poorly run company. The next day which is on the 9th I sent a message asking whether they would be refunding me or if thy would be sending me the correct part. I also sent them details about the radiator dimensions etc. so that I could ensure they got me the correct part. They rep**** with "Aprinah will contact you"... well the next day (10th) I had still gotten no response from Aprinah so I asked again and got the same reply "Aprinah will contact you". On the 12th I had still not heard from them and had completely lost my patience! I tried calling but was placed on hold until I ran out of airtime! almost 30 minutes! I sent them a stink message and told them that Aprinah wasn't doing her job. I then proceeded to purchase the radiator from a supplier down the road (which is what I should have done and will do from now on as it worked out cheaper, faster and far less hassle) On my way home I get a call from onlinecarparts, its Aprinah calling to let me know that they haven't received the radiator that was returned and that they were sorry etc. I just let her know that I had already purchased the radiator from another supplier and would like a refund and she agreed. On the 19th (7 days later) I checked my account and the radiator which cost me R1150 was still not refunded so I sent them and email enquiring about the refund and got a reply "Your refund will be processed tomorrow". On the 26th checked again and still no refund... enquired again... this time I was ignored.
