Damage to property

On Friday 22 August 2025 at around 08h30 in the morning I visited Builders Warehouse express in Wonderboom to buy cement and paint. After concluding my purchase I was directed to dispatch to load cement. The 2 guys assisting me asked to open the cover after i opened the tailgate. Before i could open the cover, the one guy forced open the cover and damaged the clip of the cover. This was reported to the manager and incident recorded in the book. About a week later, i went to enquire at the store only then they forwarded query to "complaints". For a full month now after submitting the requested documents, Grant Koopman of customer services is now giving me the run-arounds. He acknowledged that document were received and awaiting approval, now he says i must submit 2 more quotation for the clip only. I bought my cover with the vehicle at Westvaal. Westvaal do not sell the fitting parts separately and sells cover with fittings. I tried to look for other providers, they refer me to original supplier. I am frustrated and dont know where to find the clip they want or quotations thereof. please help
