was with maxshit for 10+ years, then ported over to umobile when they came out with the P70 plan. CS was pretty bad handling my case, even screwed up my porting (they didn't initiate port-out at their end), went to counter a few times to "talk" to them "nicely" for it to be done and they didn't offer me any counteroffer as well.

u mobile CS has been better so far, smaller crew at the counters, longer queue, but things get done, unlike maxis, more crew, average queue, but clueless staff
