Bad Connection and Really bad service

Im using neobroadband Wireless, i cant use my internet for more than an hour then it drops completely. ,I logged my first ticket last week monday, with no service on it, logged another on last week Wednesday with no response, I then Phoned Monday the guy said he made some changes i should phone if it happens again. Today same thing internet drops i phone in and give my reference number and then i went through all the questions, he disappears for 20 mins speaking to someone. comes back and asks me to ping google. after i said my internet works 100% and then suddenly drops. He then tells me everything is fine on his side. So i told him that i am having a problem that i cant use my internet for more than an hour without an interruption, he then tells me he will check with the LTE department after another 20mins of holding he puts the phone down in my ear. I cant pay R1500 for an internet connection that only works in periods and then receive worse support than i did with Telkom
