I want to complain about digi cause I'm very frustrated with them already

I'm UTM student and subscribed to the digi d'campus plan and at first I was charged for calling digi numbers after I made more than RM 1and so I called the customer service and they refunded all my money and say they will fix the problem ASAP (keep in mind this is in August)

And then, they've been charging me again and again until supposedly, I am enjoying free rate, but they charge me 36 cents per minute I complain complain complain until one day the technician phoned and called me "The d'campus rate supposedly to be enjoyed by those using it in the study area aka fac there but fac there sometimes I still get overcharged

Furthermore, the guys living opposite my block can get the d'campus rate and WHY CAN'T I?!!!!

I very angry and they overcharge me all the time, sometimes i keep record and find out they charged me more than RM10 until I decided to call the customer service (I very frustrated already) and guess how much they refund me this time?! 5 CENTS!!!

I called the customer service for more than a million times (hyperbole..) until now I also lazy call and make less phone calls cause I very mad at them (Make me cannot contact my family T.T and charging me more than FnF) and even chatted with them online but they aren't doing any !#!@#$@#$#@!!!

Anyone know what should I do?

my friends all give up calling CS cause every time make phone call need to call them once and wasting time listening to the recorded call.

I very angry you know, I can't call my dad as long as I want especially when he lives so far away and get charged more than FnF

anyone know what should I do?

I'm prepaid and digi d'campus is prepaid plan

Digi can be quite sucky when it comes to solving problems

But now I'm in uni and I'm not from west malaysia so I don't know where is the centre.. I planned to do so after I go back to my hometown next month T.T

Hopefully the digi centre in my hometown knows how to solve these problems
