Failure to provide service and feedback:

I asked Mr Zulu on 24 August 2015 to increase my existing data bundle from 10gb to 20gb. After various mails most of which he did not respond we went to the shop and found out that a new contract was issued by the inept Mr Zulu. He and his supervisor Charmaine Konopi promised to rectify the situation but I am not kept in the loop and they ignore my mails. In the meantime I have been billed without receiving any extra data.
