Harassment on a daily basis

I do not bank with Standard Bank or have a home loans account with them but I have been receiving multiple calls on a daily basis from their credit and home loan department in relation to outstanding home loan payments. The calls are made to my work landline, which really affects my productivity at work. As we are working from home due to the pandemic, the work calls divert to my cellphone. Now upon divert it only rings once and Standard Bank puts down. On one occasion a voice message was left to call ***. So i called this number - Spoke to Thuli on 9/11/2020 at around 12:22, explained to her what has been happening. She took the details down and said no problem the number will be removed from the profile of that creditor within 3 Business Days.

I waited out the time. Unfortunately, I still receive calls every day without a fail. I have explained on multiple occasions to the claims personnel who call that I am not the creditor they are looking for (to no end). Today (25/11/2020) I called the 086 number again to try get this sorted. I spoke to Khanyiso at around 09:02, explained everything to her, she said she will check the system and then asked me to hold, I did so. She then decided she cant help me but didnt let me know and just transferred me to someone else (Tsholofelo) at around 09:20. I had to explain the long story once again.

Tsholofelo was helpful but said she cant access that profile she needs to transfer me to the Credit department. She did so and I was transferred to Barbara. Barbara immediately asked me for the account number or my ID - I explained to her I am NOT the creditor and I do not have access to the creditor's personal information (why would I?). She then said she is not able to help me and that I must get the account number. Please can someone at Standard Bank explain to me how I (a third party not connected in any way to the creditor) must obtain their account number or ID number?

This is appalling Standard Bank! Do you not check the details of your customers and ensure that it in fact belongs to them! Now I must endure multiple daily calls. Appalling FICA processes and appalling service.
