Repairs done on my phone **********ly without my authorization!!!!

Ever since I insured my iphone 6 in 2014 with Finirite I have never had any joy from them. The most recent incident involves them repairing my phone without my authorization and then furthermore refusing to give it to me once I had paid a previous oustanding excess amount from a prior repair that I was never advised about initially. For the prior repair I finally received my phone after taking it into repairs( after a huge battle with finrite and their consistent poor service), and it was released to me without me having paid an excess(which I was never advised o pay-how can a store(edgars)- release my phone to me if I had to pay excess?!!!! I don't know-again ********** service from finrite and Edcon. I again had the misfortune of having to take in my phone for repairs with finrite on 05/11/2018 and I was hesitant to do so based on my horrific history with this insurance company-I went against my better judgement and handed in my iphone 6. On 12/11/2018 I received a call from ********** 456 at 10:25am on my ********** 9816 number where I spoke to a lady who advised me that in order for my phone to be repaired I need to pay an outstanding amount of R1200 from the previous repair(that I was not told about) and another R1200 excess for this repair. I then stated that this would be too expensive for me- I will however settle the prior R1200 and not repair the phone. She agreed-or so I thought. So today on 17/11/2018 I made my way to edgars sandton and stated that I would like to collect my unrepaired phone and settle the outstanding amount and furthermore cancel this sorry excuse of an insurance cover. I settled the R1200 from the previous repair and wanted to close the account and leave edgars/finrite for good.The sales assistant brought out the phone and to my surpise and dismay the phone is repaired- and now not only does finrite/edcon want the R1200 from the previous repair to be settled, they now want another R1200 excess for the new repair which I explicity said I was not authorizing- but they went ahead and repaired the phone. I am beyond livid as this is ********* and boarderline ********-as finrite **********ly repaired my phone without my authorization or knowledge. To add insult to injury after I settled the amount I was told the phone cannot be released as finirite refused to update my phone status because of the outstanding R1200( which I settled in store today 17/11/2018), So now not only has finrite/edcon **********ly repaired my phone without authorization, they have now essentially ****** my phone and want to ***** another R1200 from me. I don't know what kind of *****ed insurance company this is but I want nothing to do with it. I want my handset-and they can reverse the repairs and put it back as it was(broken) as I am not willing to pay an exhorbitant excess(the excess is more than excess for a car windscreen at R800!!! ridiculous!!!) amount for a repair that I did not authorize. I believe the calls are recorded and if you listen to the recording I made it very clear that I DO NOT want to repair the phone. If this issue is not resolved ASAP I will happily report this ******** activity to the ombudsman by the end of the coming week and get justice that is due to me.
