Horrible service provider

I've been attempting to contact Easypay, SADV, and Vuma regarding my Wi-Fi payment, but unfortunately, I haven't received a response from any of them. Despite verifying with my banker, who confirmed that the payment was successful on their end, I remain without assistance. It's been over 24 hours, and the constant referrals between the companies haven't provided a suitable solution, causing significant frustration. Could you please assist me in resolving this issue or provide a refund for the payment made? My Vuma router number is: ***3B238DAF Easypay reference for SADV is : ***
