Customer Caring company costs

Could you please explain to me why after 3 weeks my account is still not sorted out. I have been to the Springs mall ever week for the last 3 weeks to get the phone account sorted and to date I am still told that the R68 that was outstanding on my account has still not been corrected and is still outstanding. I paid it that day in the stall and that same lady is still helping me. She too can’t understand what the problem is on your side in the accounts department is. I have wasted petrol, time and my efforts trying to get this thing sorted out to get a phone for my son. It is the second time I am having the same problem with Vodacom. In December last year I opened an account for my daughter and had the same issue. It seems as if it is only a short payment on your side when I want to open a new account but never when I pay the account. My statements and invoices are always paid as per the total balance. You people are a ******* and here after 10 years with you I have always said I am happy with you. I am actually very disappointed in the serves I receive from Vodacom. As my accounts come to an end I WILL be moving them over to another provider and will advise every person I talk to, to do the same thing. I will do my best to let the whole of south Africa now what kind of service I have received from you.
