SADV USELESS AND SEEMS LIKE A ****

My mom has been trying get wifi with one of your suppliers SADV. We had been advised we needed to fist pay before they can install. The payment was made on the 14th August 2025. We had not been able to get the installation done as no one got back to us, they say they called on the 14th but there is no call log on the phone, so we had requested a cancellation on the 22nd August 2025. We had been advised that it would take 14 working days for a refund and That we needed to send through the id , pop and a bank confirmation letter. All this was done, now each time we follow up which is trough an annoying whatsapp chat we must repeat everything over and over again. We were advised that we cannot contact the accounts department. We want our refund ASAP. SADV IS USELESS AND THEY ARE BRINGING DOWN VUMAS GREAT REPUTATION WHY DID YOU PARTNER WITH THEM. THEY NOW WANT TO TELL US IT WIL TAKE NOW ANOTHER 2 WORKING DAYS THEY DONT SEEM TO KNOW WHAT THEY ARE DOING AND THIS IS REALLY FRUSTRATING ESPECIALLY SINCE MY MOTHER CANNOT HANDLE UNNECESSARY STRESS. WHERE DID YOU SEE A COMPANY ONLY HAS A WHATSAPP LINE AND NO OTHER NUMBER TO CALL.
