Complaint

I recently made a payment for my subscription to Vuma SADV and there is no confirmation that I have paid from their side, they usually send an sms that I have paid and the wifi would start working but this time it is not working. I have tried to contact them on WhatsApp, I sent them the proof of payment and my bank statement from Capitec. I have been waiting for their feedback since yesterday morning. I also sent SADV an email but I didn't get help.
