Mtn customer service is non existant

I requested itemized billing on the 8 November and since than sent numerous requests and follow up emails, each time been told its escalated with a new reference number. I needed it for my insurance claim however the insurance company only gives you one month for all documents to be in or the claim becomes not valid. Its now the 19 December and i still have not received the information. I have lost out on the claim and do not have a phone, is mtn even bothered.
