rude and nonsense service

i have been buying gift voouchers for clients as we no longer can hand deliver gifts due to covid i have been using company credit cards that require an invoice for them each time i need an invoice i have to call in to the call center to have them click a release button i do not understand the point of a tab for invoices if it does not show after your purchase i have had to call for all of the vouchers i have bough from January this year its frustrating and time consuming and no one can fix it yesterday i called twice and the man did not assist i called a lady this morning who answered after i was on hold for 33 minutes and her line was so bad it sounded like a piece of paper was scrunching in her ear then she dropped call (still no invoices) i call back - on hold for 27 minutes before Luke Du Preez answers the call - i explain the situation (AGAIN) and he then decides its time for attitude and to tell me how i should speak and i asked how am i speaking - with that being said i need a copy of the recording i ask for supervisor he tells me he cannot give out the supervisors name im sick and tired of calling and begging for invoices every day 3 -4 times a day on hold each time for 20 minutes + Luke needs to apologize for his ****py attitude - the business itself needs to jack up and i need an explanation as to why the invoices cannot just be there after i make payment as the tab says it should be
