Atome, how much po interest pag 1 month ma dedelay? :(

1 year mahigit na po akong user, good payer ever since, pero something came up recently na sabay sabay gastos di ko alam paano sila babayaran ngayon plano ko sana kahit next month na lang. Kaso nakakatakot baka super taas ng interest at dami ko nakikita hinaharass sila. Pa advice naman po please.
