Terrible Customer Service

I purchase a Samsung Mobile phone and TV on the 31 May 2021. On the 14th June the PHONE stopped working, took it to the store BRADLOWS (Phoenix) the next day reported it not working. spoke to the store manager who was very rude and told me that within 7 days he will have it sorted out. I refused to have it repaired as it is only 14 days old I wanted a new one, but he said due to Supplier warranty and that **** he has to send it in. 7 days had passed didn't get any F/back. visited the store at the end of June only to find out that the phone is still in the store. I was upset and made a scene and refused to hear anything from anyone, but again they assured me that they will have it resolved. Still no feedback until I called the call centre about a week and a half ago just to follow up what is the status on ma phone and they said that it is still at the store and the store needs to release it. I was Furious this time, I visited the store last Friday only to find out that the phone is still in the store, I threw ma toys all over and demanded a new phone. They still refused to give a phone said that they don't have any phones at the moment. Too make things even worse the store and the call centre don't even know the number of the supplier, who will be collecting the phone for repairs. They promised to give me F/Back by this week, so waiting for their response which I KNOW WON'T HAPPEN UNTIL I CALL OR VISIT THE STORE. Very Poor customer service from BRADLOWS (PHOENIX). Not a happy customer.
