Vodacom useless finance department

getting a contract on Vodacom is the worst decision one can ever make they dont send statements so u can understand whats going on because you always owe them even when you paid they overcharged me for way more than agreed on the contract and told me it was because of the Vat increase couldnt they notify me via sms or something in time and you go to thier branches and the cant give you answers because they have limited excess to view anything they dont notify of new charges you have to find out on your own whats going on and the call centre agents as well as consultants in the shops are clueless and not well trained Vodacom has the worst finance department im tired of going to the branch every month to fix something that cant be fixed this month i changed my debit order date any before the money was due i got a sms saying im in areas and when i called the call centre i was told i have to pay alomst double of my monthly fee agreed on and i dont owe them the girl seemed not to even pick up on the system that i changed the date then later corrected herself saying it will debit after i told her the exact date but still i have to pay money that i dont have or owe them without any explaination wow they are the worst its like their systems arent even linked they speak different things all the time
