Extremely Unsatisfied with Rain

I am extremely upset with RAIN. I have been without Internet for 7 Days now. I reported the issue to "ask rain" immediately, nevertheless to say I have received six Referance numbers and used R100 airtime on calls. I received a mail from the technical team yesterday (30 April) with instructions to reset the APN, which I did Our Internet was back on from +/- 14h00 until about 02h00 this morning. My monthly payment to Rain has just gone thru. It is 16:22 and still no joy from RAIN. I am suffering big losses as I cannot perform my duties without Internet.
