Frys electronic Frys worst customer service Plano Texas

Before my brother in law went on vacation, he and myself went to  Frys Electronic to buy a 55 inches TV. After buying it, I set it up for him, but he did not have chance to watch it, because he was busy for his vacation. When he came back, he recognized that the TV was small, therefore, we came back store to ask Customer Service if we can return and buy a bigger one. One of customer service looked at my receipt and told me that it has passed 30 days, so he can not accept return for refund, but he will accept for store credit. Next day, we packed it up and brought to store to have a bigger one,

We met one of manager at customer service, we told her about that the situation and we want to return our TV for store credit as one of their customer service told us a day before. The manager kept asking who was the manager in previous day, I said I don't know but she kept asking about the previous manager in very rude voice. I said I don't care who was the manager, and I dont want to know  who was the manager, I just came to ask their customer service and they said yes, therefore, I come back to return or exchange our TV, why do I care about who was the manager, and then she declined and said she won't accept return because it passed 30 days.

I don't care about their 30 days or not, the problem is when we came to store to asked if we can return it, and one of their customer service said yes with store credit, therefore, we packed up our TV to bring in for return. They wasted our times and they have worst customer service, even the manager.
