HSBC Branch Customer Service Representative interview questions

Online application, situational judgement test then they phoned me and asked some brief competency questions. They then arranged a telephone interview where I was asked six competency questions. The interviewer said I did really well and I had passed that stage and someone would be in touch to let me know if I would be invited for a face to face interview. One month later and still heard nothing I phone have (who have no number for resourcing or recruitment) and spoke to someone who said she would pass on my details to her manager who would try and get them to the right person and "hopefully" someone would be in touch. Around a week later they updated the application status on the career page from Phone interview passed to application unsuccessful- though still didn't bother to contact me. Highly disappointing way for such a big company to treat people, no care or respect for an applicant in this case.
