Poor service

Vuma is a **** guys, every week for 2 to 3 day there is no internet on my wifi and at the end of the month they want full payment. I use wifi 4 days a week each week because the rest of the days is "connected without internet " and when I send what's up they take too long to respond. I'm so disappointed 😞. I thought this is the best company clearly I was wrong.
