Another corrupt Municipality

Yet again another municipality in the limelight for the wrong reasons. My parents sold up their property in the Uthukela District Municipality in 2019 and moved out in January 2020. My dad applied for his refund for deposit he put for utilities the same year 2020. He was informed that the refund will be given within thirty(30) days. One(1) year and five(5) months later and he is still waiting. Every time he makes an enquiry, he is told that they will look into the matter and get back to him. Instead of a refund they send him a utility bill for a reading on 23 April 2020, when in actual fact he was already residing at their new property in Durban. Their property in the Uthukela district was sold and the new owners took occupation in January 2020. When he made a recent enquiry the person on the line told him to just stop complaining and pay the bill. Both my parents are on old age pension and this practice by the Uthukela municipality is atrocious and the fact that they refuse to refund my dad his deposit shows how deep rooted corruption is in many municipalities in the country. I always thought that this sort of practice will stamped out by the government, but allice this is not the case. When will they stop running the country down, is there any accountability or oversight.
