Bad service via Mitchell Indepth Customs

I ordered a Paramount car Radio from Mitchell who has been so helpful honestly in the beginning but this is what happened later on. 30th November 2023 delivery were booked through Internet Express under a wrong name "Pieter Bredenkamp" even though my details were given to him when I placed an order online. Courier the kept the item for days irregardless of them having to ship as soon as possible. I was travelling by then so I ended up travelling without the radio for the weekend. On the 5th of December they delivered the item after I called Mitchell, Bobshop where he seem to place the order as well as the courier. Mitchell also made me call Bobshop even though the order were through him. My order was always left behind I do not know why. That's with the courier and Mitchell managed to sort that out although it was late. Upon installing the radio it was doing whole lot of funny things, Increasing the volume full, muting etc. I reported the matter to him and he spoke to Paramount they advised him I must do software update which I did and it got worse. I stayed with the radio hoping it will get better and nothing. He then booked a courier to come pick up the unit to return it to Paramount and eventually we agreed that on the 22 December because I will be closing it is better to rather come bring the radio to him in Boksburg maybe he will take a look at it and do something or disassemble it and send it through to Paramount. He did not cancel the courier and they came to collect the unit but I was out of the office on the 20th December if I am correct. He cancelled them only when they were there. On the 22 I went to Boksburg and I was updating him from the morning that I will arrive, when I got there he was not there. He sent me to a complex that does not have any installation centre. When I was calling him he gave me the number of a random guy who came and refuse to help me after speaking to Mitchell on the phone. Mitchell then said I must go into the market at show W23 to drop off the radio and not have any radio till January 2024 because Paramount is not operating. He then told me also that there was another guy day before who had the same issue and he thinks it is Paramount's factory fault. I asked him why did he allow me to drive 50 KMs to come to him when he can't make means to help me he then told me he can't to anything to assist, it is either I leave the radio and buy a temp one or I keep the faulty item till the following year. I decided to return with the faulty radio but went to see the shop he referred me to but they didn't seem to have mutual relationship with him. As I walked out of the market and called him he said he heard a guy's voice that may check the radio for me. I gave the guy the phone and he also said he can't help me as Android radios are problematic. I left the place and Mitchell told me he will get his finance team to reimburse me my petrol money and time wasted going to Boksburg to see a ghost. He then kept quiet for many days till I reminded him of both petrol money and Unit collection. On the 23 December I had to buy another radio and get it installed cos that one was worse. He gave me Internet express Waybill number on the 29th December for collection under his own name but used my company as the collection contact even though I told him loud and clear that I am going to be home for the rest of January. I don't know where they will find the radio at the company. It is not the 2nd January 2024 there is no movement on the courier side and no petrol reimbur*****t. I do not know whether I should say this guy is good or not.
