Never ending nightmare!

I've been having endless problems with this bank. I so regret taking up a loan with them. I am now literally paying for what was a mistake on their end. I was debited early and the debit returned. I am not struggling to get my ITC profile amended. They require an ITC report from me at my cost for something that wasn't my fault!!!! I am now at my wits end, every time I receive a call from them it's only more problems but not one solution.
