vodacom airtime advance

i have been barred from the airtime advances service and i have been using vodacom all my life, for only R5 rand, this is pathetic because i get smses everyday about this blady advance but i cant use it, how can you send me smses knowing you have barred me out from the service, its been 3 years now and still cant use this service, what can i do or what is the way forward because i will definately be porting my number to a differant network coz you clearly do not care about you loyal customer, please assist with this query if not then GOODBYE!!!!!! my name is tracy royland and contactable on ********** 880 and if you do not get back to me i will write on hello peter everyday.
