Positive balance negative service

I have lodged a complaint *** on 15th November and to date no response. Furthermore my issues remain the same, having purchased airtime but not being able to call sms or use it for data. 173 constantly cuts you off!<br> <br> I am at my witts end with the poor level of service received in both aspects! Why pay for a service when there isn't sny! <br> <br> I expect either compensation or detailed explanation as to how this happens all the time. Positive account balance yet one can't use it for anything. I have screenshots of this as proof<br> <br> This is poor for an international company who can't even look after its loyal customers... time for a network change I'd say!
