Electrical goods non-returnable/Incorrect part supp****

I called the Midas Reservoir Hills Durban store (monday 22 Jan 18) for a sensor situated on back of engine block of my toyota camry. I gave sales agent all vehicle details and he says he has part, I sent my brother after work the same day to purchase part as the store was on his way. Only to discover part does not match the one I intend replacing. Part is unused, looks similar but is incorrect for the purpose it was intended for.

My brother tells me that sales person a young man, told him if part was incorrect bring it back, after paying for part and leaving store, another salesperson told him no returns on electrical parts, this was as store was closing 5pm.

I found this out after realizing part supp**** does not meet my requirements a few hours later at 7pm same day as my mechanic friend of mine removed sensor from my vehicle and compared it to midas part supp****.

Well no way of using the part, it was wrong part, now if i take this back to Midas i expect to be told part is non-returnable electrical part. Midas seems to be writing their own Consumer Protection Act rules and there employees make up policies as they go along.

I want to return the part and get my money back or have Midas provide me with the correct part . I afford Midas opportunity to resolve return of incorrect part amicably before taking matter further.
