Sasol Lynnwood does not take responsibility!!!!!!

Sasol Lynnwood does not take responsibility for petrol attendance whom loose and do not replace your petrol cap, I have laid a complaint with Ryno a young manager at the Sasol Lynnwood ridge garage and he said he would call me back, after 2 weeks he has not called me, I had to call him back. I spoke to Daisy a representative from Sasol complaints, on the video footage it apparently cant be seen if the cap was replaced or not, and it is not their problem as there are notice boards setup that states they are not liable, all they want is your loyal support and money, but should they loose and not replace your petrol cap it is on you not them. After phoning Ryno (the manger) again it was arrogantly put that the owner by the name of Gordon would not be available for me to speak to and that they will not replace my petrol cap... do you think I would go thru allllll this effort if I lost the petrol cap myself RYNO! As that was what you basically said to me. After years of loyal support I will not leave this matter here, it is time that garages take responsibility for the team that works for them and not sift blame to the customer.
