Transferring Address

I never wrote on any websites but this time I had the worst experience in my life that I decided to write on here. I went to an Xfinity store and told them to transfer my address two weeks before the move. The agent did not know anything and even though he kept asking other employees, he ended up making a mistake. When I wanted to activate our modem, they told us the agent disconnected both plans. This was the second time he does this in three years. I've been to Xfinity store two time in my life to transfer the address and he did the both times and messed it up. I can't believe an employee who doesn't know the most basic thing and did not learn after two years is still working there. I have been on phone with Xfinity for at least 5 hours per day for the last two weeks and they still could not be able to fix our plan. Also, after one week an agent was like don't worry I fixed it and I figured she activated the address we had three years ago. I have no idea how she even found that address even though I confirmed the address with her 3 times. None of the agents know how to fix a plan or transfer and they all say different things. Maybe you should do a better training for the employees so customers won't have to be on phone 5 hours everyday and still have problems.
