Poor customer service for premier banking

I have logged an enquiry regarding me not being able to pay for Uber rides via my premier account, as i received a reference number as per below:

We have received your query and would like to advise you that your team of bankers is processing your request. Please expect a response within 48 hours. Your reference number is CAS- ********** -R4X8N2

This was done monday and the same day a giy called me and informed me that the issue was resolved. He mentioned that there was a dy where the system was offline and my account was affected but that was now all sorted and i would after his call, able to pay uber with my card.

After trying to test it i found that the problem was still occuring and on the same day i sent an email to ********** and up until today i have not yet received a response.

I would hate to have to close my account for such a small matter, however i am seriously considering it now after your failure to resolve my simple query.

I would like to receive a resolution before the end lf business day tomorrow. My details are as follow:
