They won't pay your claim. Such a joke

I've had a terrible experience with these guys. On the 24th of November my car tyres were damaged as I was trying to enter Leroy Merlin Little Falls and they promised to pay for my tyres if I buy own tyres, like they will reimburse me. It was myself and other two guys that were affected. Two weeks back they asked us to forward our banking details and invoices for tyres, saying that they payment systems run on Thursdaya. Today is the 2nd week and they were supposed to pay me today as they promised yesterday, now they tell me they missed the payment run for today (07-12-2023) and tomorrow and they will let me know when they will be paying laster today or tomorrow. I'm very frustrated, and they don't take our calls.
