Pathetic service Gaydons Motors Sa Durban

Good day. I recently purchased 4 shocks for my vehicle from Gaydons Motors Durban. Just over a month now and the rear shocks are leaking. They had a dispute on the phone with me yesterday regarding the shocks and that it will take up to a week to sort out. They picked up the shocks yesterday and this morning received a call saying the shocks were damaged on fitment. When the shocks left me yesterday there was no damages. The shocks was fitted by myself. I know there was no damages to the shocks. They say there is no warranty on the shocks. They are rude and the service is pathetic. I am a qualified technician and I know how to fit shocks , Matthew says it was fitted incorrectly and damaged. It is an accusation from them and I did not damage the shock on fitment. Hopefully can get some assistance.
