Capitec Bank and blu voucher committing ***** and *****ing customers money, working together.

I purchased 2 blu vouchers on my capitec app and never received my vouchers pin code and I have been calling them along with blu credit deals and not one of them can give me my voucher pin codes or my money back I am really tired of this poor services and my money being ****** by my own bank when I call them they say the vouchers have not yet been redeemed but both of them can't give me my voucher pin codes that's is really pathetic I mean how can they sell something and then apparently they don't have the authority to give me the codes but also refuses to give my money back I have all the proof on screenshot and bank statements never have I received such poor service
