EDGARS....non-comprendo

So my wife has an Edgars account. And she used to buy on it. I hated the statements, as I could never quite understand the "Balance Due", Balance Owing, Currently Due scenario....So we paid it up and have since paid cash should we purchase anything there. Until a few weeks ago when she receives a threatening SMS about how they're going to hand her over due to non-payment of account. WOW!!! What????? And so began a torrid time of fact-finding and empty promises by EACH AND EVERY CALL CENTRE AGENT, MANAGER, TEAM LEADER, ETC ETC ETC. What was bought?? A data and airtime subscription, which we "telephonically" entered into. NO SUCH THING. Ever. We had never signed up for any of this. They promise to reverse the transactions, and apologise for the misunderstanding. My poor wife has had threatening calls and text messages on a DAILY BASIS. NOBODY CARES. She tells each person the same story, receives a reference for her call, and repeats the same thing later that day, or again the following day. Even in the evenings she's getting called about it. NOW WE ARE DONE!!! EDGARS: SHOVE YOUR BUSINESS AND NEVER CALL US AGAIN. HAND US OVER IF YOU MUST. BUT STOP CALLING. GET LOST. WE OWE YOU NOTHING. NUDDA. ZILCH. COMPRENDO????
