Usually, credit cards will be frozen with bad credit records. If there is a bad credit record, it is difficult to increase the credit limit. Your current credit card limit is zero, so why don't you just cancel it and apply for another one at another bank, or you can ask the customer service of the issuing bank if you want to keep it. This is the best way. I suggest that the landlord can save money first and then apply for withdrawal after a while, which will not only cover the bad records, but also get a higher quota. I hope my answer can help the landlord!
