Webafrica *******ly deducting money

I am absolutely taken back by the service of webafrica, I have canceled my account with them within June 2020 and they have sent an email stating that my account will be canceled from 1st August 2020 I had paid cancelation fees and paid for the month of June even though I was not using the account. They then decided to deducted R2724. 00 from my account on the 1st of September without any indication as to why or what it is for I am now struggling to get a hold of Webafrica there is no one available to assist I have Been on hold everyday since the 1st of September for 30min without any help or and replys to my email. I will not advise any one use Webafrica as a service provider as I feel they are *******ly and ********ly deducting money from they customers account.
