Ignoring letters of Insolvency

I am under the process of insolvency and have a letter from the lawyers regarding the process and that I am unable to pay anything. African bank is the only company that didn't want to accept this and didn't want me to email them the letter from the lawyers. They keep on deducting money from my account every single month while I am on this process. This is UNACCEPTABLE and I will take this further.

This is really pathetic service..
