Hi Elaine, thanks very much for your question. My name's XXXXX XXXXX I'm going to assist you with it.
Ordinarily English courts are reluctant to provide damages for distress and inconvenience in circumstances such as these. However, the Financial Ombudman (who deals with complaints about banks and other financial institutions outside the courts) takes a slightly different approach.
Distress and inconvenience over a prolonged period which causes more than minor annoyance and leads to severe disruption and wasted can result in a claim for non-financial losses to be upheld. According the FO's guidance, where distress and inconvenience is sufficient enough to warrant compensation, the amount is likely to be around £300. Exceptionally it can exceed £1,000.
In the link below you can find some very helpful guidance on the manner in which the Financial Ombudsman deal with claims such as these and what they take into consideration. Armed with this you might want to write to the bank telling them of your intention to make a complaint to the FO and suggesting a figure in the £300 - £1,000 range.

Can I clarify anything for you?
