Unhappy customer with bad experience

I bought an engine on the 19th July 2025 at Spare4 Africa and that was the worst mistake I've ever done. The engine was installed but it had loud noise; then I returned it. 2nd engine didn't want to start then 3rd engine also had it's own problems. All this attempts I've been paying my mechanic to install the engine n take it out. I was the one always calling spares 4 Africa to refund me and everytime I was given stories. On the 3rd attempt they insisted that their mechanic to come to my place to check their engine n he confirmed that the engine has problems. Mind u for those weeks I've been hiring someone car to run my business. I have lost so much money from the 22 July till 18 of August. After so many whatsapp from me to them I was refunded on the 18 August 2025. Bad service with no communication from Spares 4Africa. I won't advise anyone to buy an engine from Spares4Africa.
