LTE - No service

I have been with them for 5months now, plenty of times we sat without connection, and then atleast once a month we need to reset our router and reconnect the dim with router which is really getting so boaring, and all they tell me everytime they have restarted on their side. And if i want to cancel this contract now thry want to charge me R999.00. They do nothing to sort out this problem with the fixed LTE service they provide. Sick and tired of this service now.
