Very bad service and very slow to give me feedback on a query

I am so ****ed off with FNB's service as of late. I have not been earning my ebucks since 1 September 2019 and for the past 3 weeks I have called several times being sent from pillar to post. The explanation I got is that "yes mam, we see the query on the system" I don't care about that. All I want to know is what are you doing about it. I have been banking with them for the past 8 years and never had bad service like this. I am fighting for my ebucks because I know my spend and I get a lot back usually. Can anyone recommend another bank I can switch to asap?
