No JOY anymore from TELjoy

On 29 August I've called in to change my address and also logged a faulty Dishwasher which is on Rent to own basis. I was told to send and email which I duly did. I received a reply that the address was changed, with the technical department cc'd to log the faulty unit. Retha Grabe duly rep**** that my area is out of service area, and technical to please arrange to collect the unit and so I waited. On 5 Sept I sent another email to Retha and the technical department to enquire when this would happen as I haven't heard anything. To date I'm still waiting for a reply. On 6 September I phoned in and was informed there is no call logged for my faulty unit, and went through the process to get it done and got a reference number. And I waited. On 13 September I called in again to enquire what the hold up was and I was put on hold for 5 minutes and eventually cut off. I called back and luckily the same agent answered with some lame excuse, telling me that someone will call me today (14 Sept) to arrange the pick up. I am still waiting? So I'm wondering the tactics here: Teljoy states that they are responsible for maintenance and repairs during the rent to own period, but now my 36 month period is coming to an end on 1 Oct 2022. Convenient to delay the process so that they don't have to do anything. Over this period I've paid over R12000 for a unit which is more than double the price of a new unit today. And this is not the only unit I have on a rent to own basis. When times were tough, this was the only affordable option, and when times got tougher and you fall behind in payments, they are quick to remind you that they will come and collect their units. But I made every effort every month to get this up to date as possible, which it now is now that times are a bit easier. And now that you need the assistance they claim they give, they are nowhere to be found... Can I get some joy now in the last two weeks of this contract and get this issue resolved?
