Yes! As a consumer, you had the right to not be harassed and coerced by threats into doing what you had already done anyway. The incident is a typical example of an exploitative/unfair trade practice for which the bank can be held directly liable, if you inform them of this incident and they do nothing.
So before you address a legal notice to the bank, it's my suggestion that you rather first address them with a formal e-mail/letter informing them of this whole fiasco and how it's affected you. If they make recompense, well and good, otherwise it would be the reasonable next step sending them a legal notice upon which you would be able to successfully sue.
