4th complaint without paperwork and a solution

It's my 4th complaint for the internet ****le since 1 Nov 2015. I haven't received any link from you where I supposely used data. No statement was send Nov for both phone and stick contracts. Only when I requested the URL link, a statement for only the stick, was send on 27/11. I went to east rand mall branch and logged a complaint, I filed one on your customer services as well as well on phoning in like 3 times requesting the URL. Is it so hard to only send me the proper paperwork? I'm not going to pay unless I have valid proof. I will take you to court if you do not respond in a proper manner and give proper feedback. When logging onto the stick, all the sms's disappeared. Luckily I made copies prior. You keep telling me it is an open line, why did I load data when depleted 12/4 and on 25/4 you said your data you loaded, will expire in 2 days. I have a sms saying 20/9 data depleted. Was there not suppose to be another sms telling me that I'm on your per rand data, I could have bought data. I received sms's every month but 20 between Sept and Nov suddenly no sms. I want a proper investigation and want the proof on paperwork, no more via consultants that only tells me nonsense
