My account was double debited 3rd June and to date no one can trace the 2nd payment. I've sent bank statements, proof of payments, screenshots, followed up with no progress made. I've requested a statement of payments for my account be sent to me. This was escalated to Vumatel but 2 weeks later ... nothing! The only person that tried to assist was Amber but only 1 update was provided by her on 27th June. Can someone refund me the duplicate payment of R399 or send me a statement of account ASAP! Your support is non existent. Whatsapp is a waste of time because by the time you actually speak to someone after day 1 or 2, they transfer you without your permission or explaining why and the process starts again.
