Best Buy Canada

This is the 3rd TV that we purchased from Best Buy in the past 5 years and this is the 3rd time the picture panel has given out. I filed a claim on Monday July 27th, received a call on Tuesday July 28th, that they were not going to be able to repair it because they no longer carried the part. An order was put in for exchange on July 29th. I called on Thursday July 30th waited on hold for 45 minutes just to be told that this could take 5-7 business days. I called Thursday August 6th waited on hold for 1.5 hours just to be told again that the ticket is pending. Called again Friday August 7th waited on hold 55 minutes, spoke to the rudest person, she wanted to argue with me, when I asked for a manager; supposedly one was not available. I then asked her if this takes 5-7 business days then why are we on day 8 since the request was placed. Now maybe my math is incorrect, but July 29th, July 30th and July 31st are 3 days and Monday August 3, Tuesday August 4, Wednesday August 5, Thursday August 6 and now Friday August 7 is a total of 8 days! She just continued to say 7 days over and over, when I asked her what her name was she said that she was ending the call, I asked 3 more times for her name she place me on hold for 10 minutes and then got back on and said she was ending the call and hung up on me. I am currently on hold again to see if I can speak to someone else and get her name. This is the worst customer service I have ever received. Whether today makes 7 or 8 days, the policy is to have this resolved in 5-7 business days, which we are now passed. The number that I called is [protected] special forces, their special alright, special at having the worst customer service. On hold for 15 minutes now, let's see if this will beat the earlier time of 65 minutes, or yesterday's 1.5 hours. I will be calling the corporate office as well.
