NaTis documents

I have requested my NaTis documents on the 11th July 2022, yesterday I called WesBank to enquire about them since they were not delivered yet. I was told that DSV returned my parcel because they could not reach me on the phone, so fo the bank to send the documents I must pay R75 and I told the Ofentse (Call ref no: ***) that I did not receive any call so I can not be punished for that. Everyone know the July load shedding effects as far as cellphone reception was concerned, I am not willing to be pay for sins I did not commit. I humbly request my documents I finished paying the account in May but still waiting after the WesBank wanted more business from me to do the ownership changes and I refused that I will handle myself. Is this a punishment or a squeeze methodology for business?
