We have been CenturyLinkcustomers for over 3 years. We had to fix(upgrade) our modem once since our internet was very slow. We bought the modem from Century link, now we are experiencing no wi-fi at all or extremely low speed (8Mbps instead of 100Mbps promised). We called the customer service. They checked out modem number at it appears that it doesn't support Fiber connections, which suppose to provide fast speed. Technician just said:"That's weird". Wow! Exactly what I want to hear from you! They told us our modem has to be changed. One of their agents actually came up with a proposal and little credit for us in order to keep us as their customer but next day when I was going to schedule the appointment for installation they told me it was missunderstanding with previous agent and they can not provide me the plan he described! What?! New plane they can provide us is twice more expensive. No thank you! We are cancelling our membership!
