Keeping my money

I had a Absa 24/7 account for years with absa. My first account at absa they were still United bank. Recently they told me that my 24/7 account had to be changed because they to old. Both me and my wife went to absa randfontein to change our accounts. They changed my account and this morning when i wanted to pay for the petrol i put in my car my card said insufficient funds. I said to the petrol attendant that she must try it again because i knew that there was money in my account. 2nd time also insufficient funds. I then logged into my absa mobile app and saw that out of R376.10 i had only R56.34 available. Nice way to keep my money that i worked for. I then had to use my credit card to pay for my petrol. Me and my wife are in the process of going over to another bank. Since absa never wants to help with anything and when account works 100% You need to change it to another one because your account is \old"and then you just end up with problems."""
