How is this company still functioning?!

At the beginning of the year I settled my account with Vodacom. Everything was hunky dory.<br> Suddenly, last week I receive an SMS to say Vodacom has handled me over for legal action.... ***!!?? I tried about 10 times that day to phone the number on the SMS, but it's an incorrect number. (how VERY PROFESSIONAL).<br> This morning I spoke to Lerato. She was EXTREMELY UNHELPFUL and rude. She insists I never paid. <br> I have all the emails on my system still as proof I settled the accounts. <br> I asked to speak to a supervisor as Lerato had no clue what she was doing, but the supervisor \DOES NOT WANT TO SPEAK TO ME". <br> WHAT THE ****** HELL?!?!?! <br> How do you justify handing someone over for legal action"
