Will never buy parts at Goldwagen again

Very poor service. Bought a power steering pump. Paid a workshop to have it installed. Started leaking oil within two days and had to take it back and pay the same workshop to remove the part again so that it can be returned. Refunded the defective part but refuses to refund the installation and removal which is money down the drain as my power steering is still not fixed. Lost more than 3K to install and remove Goldwagen's defective part and the refund took 4 weeks for them to process.
