Towbars

We in December had a towbar fitted at edenvale towbar when we fetched the car they told us all was perfect only to get home and test the trailer ,i pluged it in and it blew the main fuses and a board that reads the keyless entry ,which now means nothing on the car works we had the car towed on a flat bed to the dealer only to get a R7500 bill later And the towbar still not working and the dealer also recommended we not send it back to edenvale towbars so at another R4500 the dealer fixed the towbar .story sort edenvale towbars bacically walked away from the problem after they were contacted a few time They never fitted a module to the system and thats what caused the problem Which they said they had modules so why not fit it Just stay away from them they are bad
