Maxis Communications — slow internet

Internet is so slow here at my house even though i changed it to 3g.Please fix this as soon as possible. I've been experiencing slow internet most of the time. I've tried clearing my phone cache, ram and so on still don't have a clear connection plus when I'm using hotspot for ps4 party chat i often left party chat because network connection lost. Maxis is fast here before but slow down overtime even my neighbour always complaining
