Absa froze my account

Absa froze my account without any notification, why freeze my accounts with 0 prior communication to me? No emails, no phone calls, no sms. I went to the branch at fourways to complain and they requested proof of payment for the last deposit i received from fnb. I got it and gave it to the lady and up till now no one has contacted me. Even when i call customer service, they kept saying my account is good but i just cant to use my card. My landlord is on my neck and he is threatening to lock the apartment this weekend if i dont pay his rent. How do you guys expect me to survive this?
