Dishonest pricing

Called today to cancel service due to high cost.  Total bill currently $237.63 vs Spectrum offer of $106.97 for same TV, faster internet, and landline.     Customer retention put me on hold after I explained why I was cancelling.   While on hold received e-mail from AT&T telling me my plan has changed....new total $126.93.    Rep came back on line and I thanked him for the price reduction, decided to stay with AT&T even though a little more expensive than Spectrum to avoid the hassle of changing.    4 hours later get another e-mail from AT&T telling me plan has changed again?   Signed back in and now, my plan will cost $175.87!!!    Called AT&T and asked (Edited per community guidelines)?   Response was that they automatically sent that other price quote while it was being researched on their end, and that was not the real price....seriously?   Escalated to supervisor, who confirmed....yes, AT&T LIED TO ME WHEN THEY QUOTED THE EARLIER PRICE!   Not a mistake mind you, just a flat out lie that is baked in to their process...and that they won’t stand by the quote that they sent to me, in writing!  Wow......

Switching to Spectrum first thing tomorrow.
