Bad customer care

Worst ISP I have ever had!! I cancelled my contract with them as I was relocating to a new home, after which I arranged with them to pick up their router. Their courier never arrived after multiple rearrangements and then they charged me for not returning the router, which I can now do nothing with.

And the customer service is a joke, as I tried emailed them to query the payment and all the person basically said was that it was my fault that their courier did not arrive and when I tried to dispute it, the email replies just stopped.

Feels like I was ****med to be honest!
