vodacom is my biggest nightmere

i had a very bad experience with vodacom. i had an account 3 years ago where by i took a contact phone with them. For 3 months i was not getting any benefit from the account not knowing the consultant that was helping me registered the incorrect cellphone number. they rectified that and after few months i could not open any credit because they registered the amount of the phone as my instalment on credit berour , it took a while before that can also be rectified. and now to my attention the account that i closed after 2 years its still opened. still i am struggling with vodacom because i am opening an account and they want proof that the account with vodacom is paid up . i have been logging a query for two weeks now , where by i call everyday requesting for the letter to be emailed to me and they always says after 48hrs but still its 2 weeks i have not received anything . And now when i call vodacom account i always speak with a lady called Thapelo that always hang up they phone when ever she hear that its me calling again. vodacom has become a biggest nightmere in my life..
