NO RESPONSE TO SEVERE COMPLAINT

I am now 5 reference numbers from calls further, e-mail correspondance with new refernce numbers, have sent proof that I did indeed have a datalimit. And still NO RESPONSE from MTN. Not ONE call. They NEVER called back. They have transferred the dispute to a legal department of which MTN is not willing to give me the phone number. Only e-mail address. I have e-mailed them everyday. I get no response. I do not know what to do anymore. If any MTN employee reads this - please get back to me. My clients can not get hold of me and I am still presented with a R32000 bill! Some of my latest reference numbers:<br> <br> ***3<br> ***1<br> ***
