Poor network and pathetic customer service

I had then install their device on the 27th and one of the installers by the name of Given did advise that I need a bigger antenna as the smaller one might give problems, on the 29th started experiencing the same poor network that their installer Given had advised me of. On Thursday I sent an email telling then about the poor service I am experiencing and didn't receive any response to date. On the 3qst I called them and they keep on dropping my calls. Today I am still without network and unable to work and tried getting assistance in their WhatsApp line and found a rude agent who refused to disclose their name and nit replying to my WhatsApp messages when I tell them about the bad experience and the poor network I've been having since the 29th, to date I am still without network my emails aren't being attended to and I'm a remote worker and now my job is on the line because I haven't been abkw to work since the 29th to date.
