Mandos used spares Mobeni

I bought a Chevy cruze cylinder head last year September 2024 for R10 000. I discovered within a month after that the VVTs were faulty making noise and I returned it. I was told that I can't get a refund, I must take something else of the same amount. I only took some parts for R3500 and till date my R6500 CREDIT is stuck with Mandos Mobeni. In the meantime, I need my money.
