Lost Bond Document Delaying transfer / registration

I cancelled my second bond with Standard bank Home Loan Department over one month ago. There has been zero progress, which is delaying the transfer. The delay is costing us both unnecessary interests. Both of us bank with Standard Bank, using different lawyers. I have spoken to Customer Service and the Home Loans department on many occasions, as well as Complaints Resolutions, and have recordings and reference numbers for most ofl the conversations. To Date (27/07/2023 13h15) the situation remains unchanged. The bank has lost the Bond document for a 2004 Bond taken with them. Home Loans passed a request to a lady named Melanie on 07 June 2023 and nothing has transpired since. I will require Standard bank to reimburse me for all interest charges on my bond account since 07 June 2033, the time I have wasted phoning and emailing them and the cost of all phone calls. (Estimated at R250.00 per hour.) CAN SOMEONE IN SENIOR MANAGEMENT PLEASE CONTACT ME.
