re service and delivery of kirby vacuum cleaner

good day . it's been several years that elite service services our kirby vacuum cleaner. on 29 September 2020 they collected the vacuum cleaner via dsv courier services. on the 5 October 2020 they informed us that there is certain parts that needs replacing. we agreed and a amount of R2400 wAs quoted. we paid the hole amount upfront as it was promised the machine will be sent the following day. every time we inquire we struggle to get martin ***. and everytime there is an excuse. first that blamed dsv for striking. they also can't supply us with a tracking number from dsv I did contact dsv but they are unable to assist without tracking number. Saturday another lady Kate from elite services contacted us regarding the service if the vacuum cleaner and said that the machine should probably be here on Monday, so we asked for the managers number as we dont get results. only to discover martin is the manager. it is now monday 19 October 15h35 an still no feedback, no tracking number and no kirby.
