Anyone currently subscribing to the prepaid in kk?

Was trying out the new plan and got 2 prepaid to try out if it's any better than digi 2 weeks ago
At first just reloaded rm10 to get the free 500mb was it and initially first few days was decent but then at times the network would simply gone from lte, 3G, E then no signal and the location is not some remote place but in the middle of Kk town itself

Tested different devices just to make sure ranging from ipad iOS 9 to iPhone ios8 and android
So I figured maybe should subscribe to an Internet plan and got the Im20 for 1.5gb if I'm not mistaken
Still the same problem random signal lost no matter where I am in Kk area (non remote) I'm trying hard not to simply give up but no matter digi which I am using both prepaid and postpaid still offers the best coverage
Or I should had gone for the postpaid plan instead haven't try customer service maybe I should ? Lol anyway when it's stabile the speed is good even better at times since playing vainglory doesn't give me bad pings unlike digi though not always
Any input is kindly appreciated thanks
