Account service

I have been using my card and absa account for almost 4 years on the 30th of June 2020 I still used my card and account. On the 2nd of July 2020 I was unable to use my card at pnp and was unable to withdraw money from atm. When I got home contacted absa were I was informed that I must set card limits. How does my card end up with no limits? Have tried using the app and even online bank but unable to set card limits. I can't even go into the bank as absa does not allow me to take my 3 year old with me. Even have people saying that they can't eft money into my account.
