Webafrica taking money when they not even your provider

I am appalled at the service!!!!! I clearly stated NUMEROUS times that I m with my current service provider until 31 August as I have to give a month notice. They ASSURED me I wouldn't pay anything if I signed up with them while waiting for the calendar month to end with the current provider. I have received 3 invoices from them - for WHAT????? they are not my current provider??!! After holding 40min each time to speak to someone at the billings department they again assure that they amended the 'active' service to 'pending' and PROMISED no money would be deducted from my account. Today the debit order for my current provider AND Webafrica came off. R345.00 for 2 days """"service""""" pro rata???? HOW if I am with my current provider and Webafrica doesnt even own my fibre line yet???? Absolutely disgusting!!!
