Bad service by Trade Auctioneers in George

My parents approached Traders Auctioneers in George at the end of 2021 to sell some of their furniture, of which most have been sold and the money received. Then on 24 January 2022 one of Traders Auctioneers' staff came to collect a fridge, stove and an aluminium ladder from my parents' house. Up till today, every time I enquire via the father (Fanie) or son (Wayne's) cellphone, they promised me that they will provide me with an updated spreadsheet of the last 3 items, which they not done. At this stage we do not know if the 3 items have been sold or have gone missing.
