Xfinity has the WORST customer service, period!

I ordered the Xfinity internet service online in 12/2022.  My order got canceled for no particular reason.  Then I called their customer service line on 01/17/2023 to order again.  The customer service representative whose name is Arthur helped me with the order.  Then he tricked me into switching my family cellphone plan to bundle up with the internet service plan.  I was with Cricket Wireless at the time and paying $100 for unlimited family plan for 4 lines.  By the way, Cricket provides excellent service with flat rate of $100/month, no added fees.  Their coverage was great, fast and reliable.  Anyway, the Xfinity “unlimited” family plan cost $120/ month plus fees and taxes for 4 lines.  Arthur told me that if I switch and bundle up with my internet plan, he could give me a $10 monthly discount on my internet service bill.  So I beloved him and switched after going through a long, tedious process.  The mobile service absolutely sucks.  No signal, drop calls, slow data connection, you name it.  Then sure enough, the promised $10 monthly credit did NOT show up on my internet service bill.  I called the customer service line in 03/20/2023, after a long explanation to the representative and endless wait, they told me that my account was set up right to receive the discount.  They were nice enough to give me $20 credit to cover the first 2 months.  Then I saw the most recent bill, the $10 discount is not there.  So I call them again on 04/17/2023 and geo connected with the Account Manager Samantha, who is extremely rude and disrespectful.  She told me that it was my own fault that I didn’t read the contract correctly.  When I was trying to explain to her about my conversation with the representative on 03/20/2023 and got $20 credit for the matter, she responded that she was in the conversation so she didn’t know what was going on.  She also told me that the representative I talked with on 03/20/2023 was a outside contractor and did not represent Xfinity.  She told me that it was on me and there is nothing they would do to fix the problem, even their manager would tell me the same thing.  Well, she was darn right about that.  A manager called me later yesterday and basically told me my plan is too cheap to get the discount.  I understand that Xfinity is a huge company and doesn’t care about small customers like me.  But the way they handle business is going to hurt their credibility and reputation in the long run.  None of the employees cares about customer service whatsoever.
