Terrible Vumatel Service and Fly.cool

Terrible service, my fibre has been faulty for more than a month now just when I finished paid for it and I reported, I was promised that the techs will be sent to investigate. Till to date no one has came yet I paid for the service. They have blocked me on their watapp communication line, and they ignoring my emails when I'm asking for a refund. They still have a nerve to remind me on my next payment while they service is not even functioning. Never again will I have a contract with them.
