Dubai hotel nightmare!!

Mongezi Madiba from flight center in fourways pineslopes was my agent that assisted with everything. I was booked to travel to Dubai on the 7th September 2018 but because my visa came out earlier than expected I asked to leave earlier and I made changed to my book to travel a day earlier. Because of the cancelation policy I was advised to pat R1200 to change my flights. I arranged accommodation for myself for the night if the 6th and Mongezi arranged that my transfer from the airport to the hotel be changed to accommodate for the new changes I made. Mongezi advised me that I was booked in at the Four points by shereton hotel down town and I was to make my own arrangements to get to the hotel on the 7th. Indeed on the 7th of September around 7:30pm- 8pm I went to the four points by Shereton dubai downtown to check-in and was advised that my name was not on their system. I was told to take a cab to Bur Dubai to check in at one of the two four point Shereton hotels there as I was booked in there. I therefore took a cab that costed me +/- 40 dirhams to go to the hotel at Bur Dubai, I got there and told the lady that was at the front desk that I was booked at a hotel I did not like and was not aware that Mongezi booked me at Bur Dubai and not the hotel down town. Bur Dubai and Deira are not downtown they are not in the city they are outside of the city. The arear is very busy and has shops selling things till late and lots of people going up and down outside of the hotel, if I were to relate it for you it is exactly like Johannesburg CBD or Fordsburg. I told the lady at the front desk to cancel the booking and she said she cannot cancel it because the booking was not done by them directly but by an agent, she said I should contact my agent to cancel this. The lady therefore checked me in and told me I need to make a down payment of 300 dirhams for the “tax” , I went up to my room took a shower and went down with my luggage to tell them that I will not be staying there. She asked the gentleman that was with her at the front desk what she should do as I was not prepared to pay 300 dirhams at I place I will not be staying, they therefore agreed that I pay I 100 dirhams. I therefore gave the lady a the front desk the room key card and told her I will call my agent the next day to contact them and fix the mess. I then got another cab back to the four points downtown to meet up with friends as we had arranged to spend my 1st night in Dubai at my “hotel” which has a club on the 43rd floor so it was going to be convenient for me to just go upstairs and have a few drinks with them. Mind you at this point I do not have a sim card nor did I arrange with my vodacom network to set up roaming. The following day I called Mongezi to advise him about the whole ordeal, I do not know what transpired between him and the hotel after letting him know about my problem. At this point I was on roaming . I therefore organized a local sim card the Sunday so that I can follow up on the matter however he was not at work so I could not get hold of him. On Monday I called him again to find out what is going on and I was advised that he was looking into the matter. At this point I was staying at my friend’s apartment while I get my agent to fix my problem. After being accommodated by two different people in Dubai my vacation eventually came to an end and I came back to south Africa. When I contacted Mongezi to find out what happened he said he was still looking into the matter for me, Eventually on Monday the 1st October I got a response from Mongezi telling me that I will not get refunded as I checked myself out of the hotel and I do not fall within the cancelation period, I was supposed to cancel on the 5th of September in order for a refund to be granted. How do I cancel my hotel on the 5th if I was meant to check in to the hotel on the 7th? Does that make sense? And why I am being told now that I checked myself out when the lady at the front desk said she cannot touch my booking only my agent who booked me in can make changes? I am really not happy, I was not happy when I got to Dubai, I was not happy during my stay in Dubai I was constantly worried and ended up using more money than anticipated on airtime to call you and taxis to go up and down when I arrived.
