BAD SERVICE WITH NO FEEDBACK

For the past 3 weeks i have been calling and even went to the store, to try and find out if i qualify for a contract. The customer care consultants could not assist me, jusy saying i do not qualify. Then a gentleman from the Durban branch called me to advise there is a block/lock on my ID number due to an account i apparently had many years ago. I requested how this matter could be resolved and all they said was they would need to email the necessary department that deals with it. It is now 3 weeks later, and to date nothing has been resolved and no one has answers for me. I think this is highly unprofessional as no one is assisting me regarding this matter. What does this tell me about the company in general? Would you want to do business with a business like this????????????
