Poor service

I bought something online during February 2023, which appeared to be a ****. I requested FNB to reverse this payment on 24 March 2023. Since then I sent numerous emails as well as dispute forms and proof of cancellation, proof that the comapny and emails and telephone numbers does not exit. Still FNB only send be emails back to ask for the proof as well as the dispute form that I already sent about 6 or 7 times. This is now 5 months later! FNB does not even read the mails of check the attachments. Very poor service. Will not refer anyone to them
