System offline

<p>I called vodacom today in the morning , my grandmother is the account holder. My grandmother answered all the security questions and I had requested for all data recurring bundles to be removed however the system was offline they said hey would call me back in 10min but I didn't receive any call back ....I decide to call back now and spoke to a consultant who told I can't be assisted because I'm not the account holder however it's not my fault that their systems went off and I shouldn't even need to call back when I was promised a call back.... I'm upset cause I woke up my grand mother early in the morning so that they can conduct their security questions. I was evendors late for work ....my grandmother brought this phone for me and I've been using it for the past 10 years yet we receive such poor service ...the phone number is ********** 664</p>
