not treating customers fairly

I am really upset that you proceeded and forfeited my airtime without even a notification in advance that my data is about to expire as you used to do- this isn't in line to treating customers fairly infact more sneaky and devious on your part. In this day and age, people depend on internet for personal and business relations and for me to be told it will be logged and take 5 days for someone to only tell me why I didn't receive a reminder is unacceptable . Went to your canal walk branch and lady logged this and still not satisfied especially on waiting period (very detrimental as I buy bulk data to use internet for important things), I asked to see Manager who only availed himself 20 minutes later- not good especially if you are not going to get a favourable answer. Big companies like Vodacom are supposed to give on time real service. Ok say you see you didn't send the reminder (which you really didn't) , then what??. I want my data bundle credited back asap- I risk to lose out on a lot without it and after that, it better for me to port to a service provider who cares about treating clients fairly
