Refund

Hi

I bought anew turbo charger for my bakkie on 8 February 2023, my mechanic already got another one for me, so I decided to return the new charger to the company below on the 9 February, I contacted them and spoke to Denise and manager Ricardo, both told me about the 20% handling fee which I agreed for them to remove from the amount I paid, on the 10th they called back and said that there MD refuses to take it back even though it's sealed and returned within the period stated at the bottom of the invoice

Today the 14th February I tried again wit the manager Ricardo to speak to his MD, I even sent the turbo back to inspect and show them that it's sealed and new, they said the MD is still refusing

If u look at the bottom of there invoice showing there terms and conditions which I agreed to

Please can you help in getting my refund as I need to pay the mechanic
