Hi,
I have been buying calling cards from
http://www.bestphonecards.com.au from many years and never faced any problems with the calling cards and i have referred many friends and family and their accounts have been activated instantly. The terms and conditions , customer service numbers of all the phone cards are completely updated from time to time and now a days the customer issues are besing resolved so fast if any @ bes phone cards.
These companies are just resellers of the phone cards.. It's the telecommunication carriers who change their terms and conditions, calling rates etc.
