I’ve been having a bad Experience with Spectrum I have called spectrum about eight times, each time I waited about 30 minutes on the phone, another time 23 minutes, another time they called me back only to get hung up on from a young lady named Sierra I feel that’s very poor customer skills service & very unprofessional. Every time I call they tell you something different and then you called to ask for a manager or supervisor and you get hung up on. They’re so quick to take your money but not fix the problem. Came home from work to none of the Service that I ask for & that I pay for was working but yet I’m paying for this crap. I’m a valued customer & I work hard for my money I should not have to chase customer service around on the phone & be without my services that I pay for. Thumbs down ????

We switched to CenturyLink and could not be happier. It is so much faster, has never cut out and had the best installation customer service. The price is also great.

Continued Charges For Many Months After Moving!

I cancelled my Century Link service a week before before I moved from my home in mid-June. I went online to copy off the return tags to return their receiver, and sent that back as directed in June also. After 2 more phone calls, I am still getting charged $100.29 MONTHLY for a service I no longer receive. I’m now trying to call a 3rd time to speak to a representative but cannot get a live person. Ideas? BTW, I’ve finally decided to dispute these charges on my MasterCard. I wish I would have thought of this earlier and hope Century Link finally understands that I have moved and sent back their equipment.
