Unfair treatment and slap in my face from Capitec bank

I paid all my installments every single month and in April 2021 was put of for medical reasons.I also paid many years for the insurance that Capitecbank added onto my installments.I used the insurance for the purpose and submit a claim through Capitec banks procedures and everything at Capitecbank was paid off in full.My payments was also up to date with the bank.Later when i decided to see if i could get a loan with Capitecbank i was told there is a problem and should contact the claims department because i am a risk client.I called and was informed that the bank has put me on sequestration status because i submitted a claim.I ask them but why would you people do this because i was not in arrears and the insurance did payed you in full i also don't see the reason for this.I also informed them that once you put this on your records it automatically will reflect on ITC and credit buro.I also inform them that they are now placing me as a loyal client in a bad position and they label me as bad client.All i get is sorry but sorry is not what i want this should never have happened at all.Just because i don't work for a big company anymore does not mean i cannot pay installments.Now that you work for yourself the bank does not want to know you at all.I have put everything in my business and just needed to finance my own trailers and now Capitec bank skrew me with this.I do not appreciate this kind of behaviour from them and they don't need to treat me like dirt.
