Nedbank homeloans is just the worse!!!!!!

I have a homeloan with Nedbank since 2016. I habe been trying to negotiate a better rate to no avail. I then got a better rate at another bank. I requested a settlement quote and received one in August 2025, I opted to wait out the penalty period which ended on 17 November 2025. The lawyers want to register the new bond, but the figures they now received from Nedbank are different, slightly higher. I have been calling since Monday, and sent various follow up emails. I spoke to Abaleng, Nomasonto, Lihle and a Mr Phumlani. I have not been able to secure a reasonable explanations, I have sent emails, I have called endlessly, I have been promised call backs to no avail. This process hinders the registration of my new bond. I believe these are just delay tactics or a bunch of badly trained consultants.
