Hi, my Wi-Fi stopped working last week Monday on the 08th April 2024, it flickering a red signal on the Wifi, i logged a call with SADV on *** and was provided with a ref ***5, up until today the call has not been resolved i have been purchasing my data to remain online since i work from home, i have received calls that this reg was escalated to Vumatel and up until today this has not been resolved, this is the 2nd time im getting such poor service and yet im paying for my wifi and have never skipped a month, this has been the worst service ever>>>>>> i never want to deal with this company ever...... and i need refund for all my data that i have bought since last week.
