*********** and non existent service

It has been 3 weeks I have been trying to get an itemized bill for a data contract and still nothing. I logged it on the app called in 4 times completed voice validation and was still subjects to questions to validate me. No response on app. First call I held for 45 min and was told the statement would be sent in 2 days. 5 days later still nothing. I called to ask where statement is to be told I now have to send a written letter and id which I sent on the 15/2 I wanted another 48 hours. Still nothing.I call again held for 30 min and eventually hung up. Another call today to be told voice validation done and then the consultant still asks questions. Consultants English is appalling sounds des on the other side. Tells me request closed docs not received?!!! I am disgusted I have been a loyal paid up customer for over 10 years I pay 1500 per month and I get treated like this over 3 weeks and they don't care!i am paying for data I am not receiving and I need the data for my business!!!! Sent it again another request ha ha stupid to think this one will be actuoned
