Data query.

I bought 30 days data bundles, I tried to connect on the internet and on social networks but it never worked. I then called MTN customer service several times to query about my data I never got assisted, the consultants I spoke to kept on saying I must switch my phone off for certain minutes and did that it never worked. I tried time and again to call them so that they can fix the problem or re-embass me, they told me to wait for 24 hours they will get back to me. I waited and waited until I call again to follow up, and the lady I spoke to again told me to wait another 24hrs, I told her I did that already and it didn't work she then told me she cannot help me I have to wait for that 24 hrs again so that she can forward the query to this other department. I waited again until today no response, no call , no refund, nothing . I want my airtime back people please don't make my life so difficult, i've been an MTN customer since the first day I was bought a cellphone. I want my money back!!.
