Worst customer service ever. Don't use this ISP

If it was possible to rate them 0 i would because these people have the worst customer service ever. After waiting for days for my internet to be installed after i had paid , now they cut off the internet without any communication and when you call them there's no answer, WhatsApp then they take the entire day to reply and their support team don't even bother to reply your emails. I finally got a hold of someone on Instagram and they told me that my line was faulty and they were working on it,its been 24hours and they don't communicate this information to customers you have to figure it out yourself. Now i have assignments and courses i need to do and i am unable because i dont have internet. They don't have an ETA for when this will be resolved, its like they don't have people working on weekends because how is it that an ISP can't resolve an fault immediately or atleast provide an ETA.
