Pathetic Service by Telkom - Fed Up

I have been a happy telkom customer for very long. But their accounts department is not up to date. For the past 2 months they have taken my debit order twice. (Double the amount). And I have been getting emails and sms's saying that I haven't paid my account and now they want to deduct 3 months worth of debit orders just because they are not allocating their accounts correctly. I should be in a credit for two months with the total they deducted the last two months. I have tried getting hold of their accounts department, I then sent them an email early last week asking them to sort my account out, and received an email saying someone would be in contact with me in 48 hours.. it's been a week .. I would not recommend Telkom to any new clients and will spread the word through Social Media.
