Pathetic whatsapp service and no resolution on my double billing complaint

Pathetic service from Web Africa Whatsapp service and no alternative contact number to raise pertinent issues such as mine - double billing. Since November 2021, Web Africa has been deducting R399 from both Credit Card (Primary payment method) as well as Cheque Account (secondary payment method) for the months of November & December 2021. While from January 2022 to April 2022, they started deducting from the Secondary payment method. But they still doubled debited the secondary payment method (Cheque Account). I have been raising this matter through their pathetic whatsapp number and to date i have engaged more than 6 to 7 agents who never resolved my matter. I even shared bank statements which clearly show the transactions in question (R399). The last interaction with an agent was on the 25th Jan 2023 and no update has been provided. So disappointed with the lack of action and communication from Web Africa. Will also escalate to their CEO if they have a platform. I'll never leave it until I am refunded my hard earned cash.
