bond term been extended without my knowledge

nedbank is indebting people with this payment break that we app**** for, because of 4 months break my home loan term was left with 232 months. Now after the payment break nedbank added 18 months in my home loan account. This is insane because this term was not negotiated with me and I did not agree with it. I called the home loan department about this term of 250 months for a house that is insane. I want to move my bond to another bank because this is done to certain people. I need help in this matter and put my home loan back to 240 months term. The government said no one should make profit in this covid 19 situation and now nedbank is ripping people off. The interest charged is too much and the term is unfair to me as a client.
