Very slow in resolving cases

This a a 2nd review regarding the same matter. I wrote a review earlier this year in January regarding a TV that I did not order and receive but billed on my account. ***** Department said the issue has been resolved but till to date my statement/ has not yet been updated and every month I have to buy airtime to call you guys regarding the same issue but you failing to resolve a simple inquiry. I don't know how many escalations have been so far because every time I call the customer service I am told they are escalating the case and will be contacted within 72 hours but No one is getting back to me. Your service sucks!!!! Now I was on a call with an agent who then transferred me to the ***** Department, the phone kept on ringing until it dropped itself without anyone answering it...you should look at working on your customer service because wow!!! You are really failing dismally!!
