Poor service, once again, at ABSA Heidelberg

Good day I recently ported my ABSA account at Heidelberg ABSA branch. Encountered problem(s) and lodged a complaint online. I was contacted by the branch manager (on 02 December 2019 @ 17:25), who agreed to email me the information in question (the following day). This email, from the branch manager, to date has not happen / not received by me. This poor / non-existent service at ABSA Heidelberg is not an isolated incident. In my opinion ABSA Head Office should urgently investigate the ABSA Heidelberg branch as well as the service / lack thereof they deliver / render as I am not the only unhappy / unsatisfied ABSA Heidelberg client. Maybe the time has come for Heidelberg ABSA clients to stop with the threat of changing banks and just do it. Maybe if there is not enough ABSA clients in Heidelberg to justify a branch, the current employees working at the ABSA Heidelberg branch, who would probably find themselves unemployed would understand what a privilege it is to have a job in South Africa, one with benefits (pension, medical aid, reduced bank charges, "cheap" home loans etc.). How difficult is it to do what one is employed for (at the end of the day you receive a salary)...
