Incompetence and poor customer services

I took out a data contract in July through Mondo. The activation fees were deducted from my bank account. During August no deductions was made from my account so I emailed Mondo to enquire when deductions will be made because I dont want my credit record to be badly affected. I had no response. I received a call on 14 September that I am in arrears. I explained that my account wasn't debited and no one rep**** to my email. I was told the account was invalid but how could it be invalid whereas they deduction the connection fees from my account. I immediately paid the outstanding amount via ETF to Telkoms Absa account. I received a text yesterday that my account has been suspended due to Collection. This is absurd and unacceptable. I truly hope that due to Telkoms incompetence and lack of customer service my credit record may not be affected negatively. I need my services reconnected because I have emailed proof of payment to *** which I have made on 14 September
