Pool Acid damaged my seat

On 28 Feb purchased BLU52 pool acid from checkers on Bram Fischer road. I put the rest of groceries with the acid on the back car seat ( as I have a million times) and drove off.

I recall driving home thinking to myself that I could smell pepper spray.

When arriving home (7.7 km from the shop) I realised that the acid had spilled on my seat, my seat was still then looking ok. When I woke up the next day, I realized the extreme damage that the acid had caused to my car seat. I have attached the a pic of the seat and of the unopened acid for your referral.

The stinge was so terrible and strong that one of my daughter’s eyes started watering a couple of seconds after being in the car of which I’ve had to arrange alternative transport for both my kids. This is dangerous negligence which could have had deadly repercussions.

May you kindly on steps I need to take to get my chair sorted.
