I made a mistake of not doing a bit of reading reviews of services provided by ABC Broadband.
I am a victim now and struggling hard to get my services terminated.
If you planning to subscribe just check out the reviews related to your area.
However the CC is common I think and it is my opinion and experience that it was near to impossible to get any support.
If you have already subscribed, then try to follow up with a written email from your registered email id. It will be handy on a later date.
