WEBAFRICA - PATHETIC SERVICE

I have been trying to upgrade my line to 100/50mbps since September. I was initially on a 20/10 line and in error was upgraded to a 40/10 line. Your whatsapp contact centre is pathetic, it takes ages to get through to a consultant and when you do they can't even help you. I need the better line for work purposes and have had to delay starting my new job by a month. I was promised that they would correct the mistake and my upgrade would be corrected as at 1 November and here we are still on the 40/10 line. I have wasted so much time trying to get this resolved. Sent a complaints email but they don't even respond. There is no way I can wait another month as my income depends on this line!!!! Someone in management needs to call me back and sort this out immediately!
