Edgars Data/airtime subscription ****

I have been an Edgars account holder for a number of years, paid up my account and kept it open in case I may need it.. a week ago I received an sms saying I owe them for a data/airtime subscription, now they’ve canceled the subscription but they telling me owe them for services that I didn’t even use.. I tried calling a number of times and I was told the matter will be investigated and a query logged and now they telling me that I must go to any Edgars store to listen in to a telephonic recording... I’m honestly shocked and horrified by the level of service I’ve received from Edgars and their call center agents.. If any of the people who claim to have listened to any recording really did listen to it, we wouldn’t be here but they continue disregarding my efforts and are dismally failing to resolve this matter.. and I will NOT pay for a service I did not use, period.
