Holding refund back that is owed to me

I am doing this review because of the bad service I have recieved from Tymembank. I ordered stuff from Temu & then they refunded me of two amounts one of R193 & the other R85. All was done from Temu's side. Tymebank bank are supposed to release it. The one of R193 has been done but not the one of R85. I have contacted tymebank on numerous occasions and still nothing. They have all my contact details but don't even bother to contact me. I have even sent them proof of refund and it still has not been done. I just want them to reales the R85 and stop playing the fool. I have sent the screenshot of the refund and still nothing.
