Service failure yet again

I would to express my disappointment and frustration with Vuma/Fly.cool. I've made my eft payment on the 19th of Oct and no one has acknowledged my payment to date. My service was cut off,even though I emailed and sent a WhatsApp to client services. All I get is "sorry,we apologize, we will fix it. The level of service is very poor,how come one took time to respond and explain the delay? Looks like there's no proper structure in place to trace and allocate payment. You're only good at apologizing and not fixing internal system failures. I Demand my line to be reconnected immediately and someone needs to call and tell me that,my query has been resolved
