Poor Service and ripped my money.

I returned my hisense 65inch tv to the Game store festival mall on the 09th of December and filled in a repair form. On the 03rd of January Brandon called me and said the tv hve guarantee but i have to pay as im the one who caused damage to the tv. I understood and paid immediately. The following day on the fourth i went to the store to fetch my tv. It switched on for an hour and off again. I called Brandon and explained the situation. He said he will send someone to fix the tv at my house. We waited for a week or two and finally he came. He didn't fix the tv, he said he needs to replace some part and will order. He promised to come back after three days but he never came. I contacted Brandon again and explained the situation. Brandon said he will check the spares and come back to me. Shame he did come back to me and explained that hisense didn't have the spares and i need to get a new tv. I went back to the store and filled a credit application and they said i should wait for their call. After a week i called the atore and the hisense sales rep who is based in the store said my credit application has been declined because hisense have spares now. I called Brandon to explain that my application has been declinedand be said he will get back to me which he never did. I know Brandon is a good man shame and he is so helpful. What im asking is someone to fix my tv or get a new tv from the store. I dont need to go to the media about this or call speak out or whatever.
