USELESS DSTV INTERNET!!!!!!

Good day,Am very disappointed with DSTV Internet,I have been paying my monthly subscription for the past 2 months and they (DSTV) failed to allocate My Data,Everytime when I make follow up with them they always promised to escalate the matter and provide me with escalation reference and nothing will be done,This is so frustrating becuase Am using my prepaid airtime to hold for more than 15 minutes everyday and no resolution at the end of the day,Am GATVOL and I feel de*****ed by DSTV for they convinced me to pay but they failed to deliver,They have become useless!!!!
