Extremely poor service and incorrect billing

Have the same problem for 3rd month in a row. Requested an Itemized bill for January and had to report Vodacom on Hellopeter before I got responce. Got a bill double the amount of January for February - requested the itemized bill again and are still waiting. The phone was cut off 2 weeks into March for the outstanding Feb bill .Without sending me the itemized bill. Sick and tired of Vodacom's poor service - worst telecomms service provider in SA. After phone was cut I got a sms stating that X amount talk time and data available - so my contract amount for March was not used up. Then I get a final notice basically threatening me to pay within 7 days - also showing an amount of R1500 + for March outstanding. When querying this I was told was for data usage. How can this be? The phone was off half of the month and according to the message received still funds available on the contract. I then paid the Feb bill on 30 March (still not received the itemized bill!!!). When I asked this morning why the phone was still off was told by a very rude person that it will be put on today but if the March bill is not paid by tonite will be cut off again. NOT EVEN RECEIVED A MARCH BILL!
