Bad service

I recharged on March 1 with R30,I received an SMS that I would get 200 mb data on March 6th,by midday March 6th I hadn't received the data as per SMS,I called the contact centre and spoke to Zodwa who told me I had to recharge with R30 to get the data though I had told her I had done that already,after having made her understand this the second time she said she would logg a service request to technicians and was happy to be rid of me without taking my details,I did not receive any SMS as is the norm with a ref number,I called back 2 hours later and spoke to manager on duty Daniel Mnyande,he told me there was no service request logged and asked me how I wanted to proceed,he kept on asking me what I wanted to do,which convinced me he was in no mood to deal with me or my problem, this confused me because he works for Vodacom and not me,after telling him that I wanted him to log the query he said it was not the 'right 'thing to do as it was still the 6th,he would rather I have called the following day,upon insisting he said he would log it nd proceeded to do so,I am unhappy about the service, not from only the agent but a supervisor ought to deliver more than treatment I recievd
