Disgruntled Vumatel Fly.Cool Client

Good day. My ISP is Vumatel FlyCool. I am extremely happy with my fibre speed except when something goes wrong and I attempt to contact Fly.Cool. I have been offline since Saturday the 27th of August 2022. I sent a WhatsApp message notifying them of my problem on the 28th and 31st of August 2022. Till to this day, they have not got back to me. When I try to contact them on ***, I always get an automated response saying "the callee is busy now and cannot take your call". I just wish to state that I am not impressed at all with the after care support that I receive from Fly.Cool. It gives the impression that they do not care about our business.
