Bad service-the worst

Visited local branch on 3 November 2022. Filled in paperwork with consultants which said she had all the info and said process takes 15-20 workdays. Visited branch 2 December after no reaction. OM claimed i have not answered their email, but this question was already dealt with on 3 November. Got sms today to say they got all the paperwork NOW, and that it will take another 10-20 days. In other words since i started the process on 3 November it will be 2 months until solved. It is inexcusable. Whoever did the work on 3 November at the branch did not do a proper job. I have rated OM 's service 5x as bad and complained with customer care as well as on FB. Not once did anybody tried to call me or make amends. This is the worst service from any business i have ever experienced.
