Woolworths paid up letter

I have phone Woolworths and asked to send me a paid up letter for my Woolworths credit cad, first request was on June 2023, they said i must wait for 7 days, after 8 days I called again they said I must wait for another 7 days, I have been calling they pass the phone and I have lost my money buying airtime and nothing has happened Last week I received a survey email to rate them with their service but I have never received the paid up letter, Monday I went to the store they promised to send it In two working day's, today I went to the store again they said I must come tomorrow, I am really tired of their poor service,

Please help me to get my paid up letter as soon as possible
