Lies and deception

Having been one of the people vodacom double debited I am still awaiting the refund of the bank charges. Was originally informed it would all be done by, 5th January. Nothing! Call back the following Monday having giving them the benefit of the doubt. Over a hour later no progress passed from person to person and dept to dept. no one want to be responsible for their companies failure. Finally. Told it will be escalated and to call back Tuesday for update. Tuesday no record of the conversation. Start all over again another hour or so wasted. Promised a refund within an hour. Didn't happen. Call back informed a supervisor will check the call and come back to me, still waiting. Thursday dealt with a Prenisha who tells me Pinky in accounts was awaiting a bank statement. Which no one had asked for before. Still no refund. Today 18 December 9 people 7 dropped/cut calls. More promises and NOTHING. A call from the Twitter team! I'm tired of dealing with the mediocrity you employ, the poor customer service, get better systems and record information. I've wasted over 4 hours trying to get an answer and I'm no further forward. What more must I do for you to take this seriously.
