No response to reverse bond term extension of additional 30 years without my knowledge

I have requested for my bond term which was extended without my knowledge to another 30 years to be reversed and taken back to original term, asked for the original bond agreement signed, and th bond insurance schedule from Standard Bank. It has been a week and no response BUT I was called every day at 7:20 for a 30-days amount due of R1300 that I don't even know where it was coming from as I haven't missed bond payments in the last six months.

When one needs critical information and also fix up the account there's no response...but tables turn they autocall without caring if one is busy at work or not...this is disgusting service!
