WORST CUSTOMER EXPERIENCE EVER

This is the absolute worst store that I have ever went to. The word customer service does not exist in their vocabulary. I have taken my TV in for a repair under the extended warranty this was done on the 10/10/2020 and they had made me sign a paper stating that there is a 21 day turnaround time. I kept on calling both the store and the extended warranty lines however every person failed to give me feedback on the repair. I end up going to the store and I speak to three store 'managers'', they tell me the 21 day turnaround time is only for a normal warranty. They tell me they paid for the repair however that was only on the 18/11/2020. I ten say this is not acceptable as its been over a month now, they assure me that no refund can be made. I get threatened by the store manager to say if i don't stop asking he will ensure my TV repair takes longer, they only offer me a rental TV now and tell me that the TV will be repaid by this week. I call and of course no one picks up. This is the most annoying and most stressful experience I have ever had. I will never shop at any game store again.
