BMO Harris Bank Account Or Service Complaint

BMO Harris Bank account or service department,

Checking account Account opening, closing, or management Kansas

I went to BMO Harris Bank located at - - -, -, KS - to open a checking account. When I received my first statement I noticed the bank opened a credit line without my consent. I asked the bank to close the line of credit and so they mailed me a form to sign giving them consent to close the credit line. I brought the paperwork into the branch on -/-/2016 and was assured the line of credit would be closed. On -/-/2016 I noticed the line of credit was still open. I spoke to the branch manager and he told me the banker handling my account must be busy and he 'd talk to her about it the following week. Today is -/-/2016 and my line of credit remains open.
