Worst experience ever!Vodacom

Where do I start? Cancelled 2 of my Vodacom contracts early December by paying them of the cancellation amount almost over 5k only for them to debit me 3 x the bill amount resulting in bank charges missed debit order fee and a major drop in my credit score! Now whose going to fix this entire mess that's been created by Vodacom whilst me as a loyal client ensured I followed the process provided. Called them received the cancellation quote went into the store swiped and was advised no further debit orders! Telephonically and by the in store consultant. Almost 2 months later u debit me an amount that was not even due to you??? Yet the minute a client misses a debit you're too quick to suspend services! I will escalate this matter further. I will get to the bottom of this and I will not take another contract with Vodacom! Absolutely pathetic . Now trying to get a hold of Vodacom is like trying to find rain in the desert! Over half an hour of just trying to get through to someone only for the call to drop?? Make it make sense?!
