Vodacom contract

I got my very first contract at vodacom about two years ago. I pay the 28 th of each month ( which i had to phone about 10 time ) just to tell them again to deduct which they never did and i ended up in arrears every time! After visiting cavendish branch numourus times to pay cash every month due to vodacom not deducting and then being transfered by my work to a different area and not being close to a vodacom to pay cash and they still not deducting im obviously in arrears. Mid last month i went to pay the last total of R436 which i got via email statement cash to close the contract just to be turned away by two imcompetand employees at cavindish square branch with a nochalant attitude. Not being able to pay the amount cash and vodacom once again for the past two years not deducting i got HANDED over and to top it off i have to pay back R1300 instead of R 436 because vodacom is a dissapointing network and their staff has no intrest in assisting their clients to the best of their abilities. I got my first ever contract by vodacom just to be dissapointed for a whole two years. Now that the lawyers are phoning me i have to go trough all the trouble of having to take off of work just to get an affidavid from the police station to make sure that this can come off my name. Working for a financial institution i know how important my credit record is and with being with vodacim for two years have ruined that. Never in my life have i ever been so dissapointed in a cellular network which i chose to go with for my firat ever contract . I am most disgusted by vodacom and so dissapointed.
