I cant believe a international company can be this helpless!!

I get harrased on a daily basis by sms and phonecalls, claiming that my vehicle account is in arrears! I keep telling the operator that #1 My debit order went off my FNB account on 03/01/2022 and they keep promising to fix the error - this doesn't happen. Today Andiswa said she sees the payment reflecting on the 11th January - but claims I am still in arrears. #2 I keep asking for a statement as I have not received one since I bought the vehicle. Up to now I have not received one. The operators tell me I must send a e-mail, but it keeps returning claiming I am SPAM.
