Internet is soooooo slow

I absolutely hate xfinity. I've had nothing but trouble with both cable TV and internet ever since I started. I'm getting download speeds of 4 mega bits per second 😡They have come out and rewired at least 19 times, and have replaced the cable boxes and modem more times than I can count. I can't wait to ditch xfinity and switch to frontier which has much better and faster internet, they are much cheaper too.
