The so-called payment holiday

ABSA Send me a sms asking if you want 3 months payment relief, I answered es because I am a sole proprietor and my business is closed, then I see a shocker on FB that for the 3 months you are not paying Absa wants to ad 12 months to that clients back payments, So in my case for R18000 they want R80 000 in return, I have contacted them via email but no response, tried to phone and held on for 32 minutes with no answer, they have an option that they will call you back, nothing, Absa are keeping their clients in the dark about the real cost of this payment holiday and should be open and tell the truth about the cost on their websites, because there it only says interest will be charged, tell the people the truth about the cost, I am still waiting to hear from Absa
