Account error

My fibre account with Vodacom had an outstanding amount due to a failed debit order and thus my account was suspended. I went to Vodacom in the Brooklyn mall yesterday to settle the outstanding amount. I was assured that Vodacom will lift my suspension and reconnect my internet within 5 hours. I was also assured that Vodacom WILL NOT double debit my account. I did however spend another 30 minutes on the phone to Vodacom yesterday afternoon to make sure that Vodacom has received my payment and that they WILL NOT double debit my account. They also promised me that my internet will be working today. However, this morning I woke up to find that Vodacom did try to double debit my account last night and the transaction failed due to not having enough money in my account AND my bank charged me R185 for the bounced debit. I am not making the mistake of phoning customer care again as it took me over 30 minutes on the phone yesterday, speaking to 5 different departments to finally get any kind of assistance. Can someone please contact me asap and assist.
