How do i get a lawyer or what type of lawyer is needed?

M&T bank came to my job on Monday jan, 23 2017 to see if I wanted to set up an account through them for a checking,savings and a direct deposit.which I did on my orentationm day. I left my position 2 days later for other reasons. That Friday , my husband and I went into the bank to put him on the account, come to find out for some reason my checking account was terminated Tuesday jan24,2017 and the bank couldn't understand why. So someone from the bank named Sarah helped my husband and I to reactivate the account. M&T thought somebody from my job deactivated my account. But come to find out someone from M&T bank closed my account due to leaving my job. A man name Greg(I have his number and the adress he works for a different M&T bank) tired to tell me they tried to call my phone but my vm was full to leave a message to see if I still wanted my account.but they lied bc no1 called and deleted it w.o my approval. They violated my rights and the branch manager agreed& tried to lie abouti
