NO SERVICE

I bought airtime so that I could buy data, however I could not because 8ta credited me incorrect balance. I phone to enquire about the issue, the consultant that was dealing with my case could not find the reason why, so he escalated the matter and gave me a case member. It was 2 weeks ago but no refund, no feedback, no communication, nothing. Is this how such a huge company oparate. Am so shocked , not even an acknowledgement ams to say we are aware of your problem and we get back to you... In conclusion I am ****** and and denied service...
