Worst company

I never write Reviews this is obscured I recently went into a local store and started services with xfinity spent 2 hours at the store within three days. My services were shut off. On the app it was saying it was shut off due to a $40 balance owed. I started a chat with a live agent Nikita (since you can’t call and get thru to an actual person) inquiring why would I have a bill when I just started services 3 days prior. After on live chat with agent Nikita for over 1 1/2 hours. She assured me I shouldn't had a bill and she was restoring my services. She had sent me a link to reactivate my equipment. I was not at home at the time she sent the link so when I tried to go back to it, it was no longer visible in the chat. I did have a screenshot of it. I tried to do it that way with no luck. Spent another almost 2 hours on a live chat. They kept transferring me from agent to agent by the last agent. They assured me that all I had to do was call a specific xfinity number they gave me in the morning, they were making notes making it a “high priority” and it would be a quick call in the morning and my services would be restored. I called the next morning, another 2 hour phone call they disclosed that there was a block on the apartment due to a prior tenants bill even including the prior tenants name and how much they owe. Which how do you release information on a former customer to a new customer?? Now they are requesting a copy of the lease and a copy of a bill from my prior address. I have spent countless hours trying to just start services with Xfinity I do not believe a prior customers bill should be another customer's problem. I've never heard of a bill staying at a home and not being charged to the former customer. I should not be held responsible for the prior tenant’s bill, you should be able to resolve this issue on your end. I would not recommend xfinity to ANYONE!!
