Disappointed that monthly fees has still not been allocated correctly after 5 months!!

I am disappointed in the service I have been getting from VA! I have spent hundreds of rands in airtime in order to call them since June this year and to date my issue has still not been resolved! Pathetic customer service! seems the people from Collections do not know what they are doing or are in competent to do their job!! I have made a payment in June on the 13th towards membership and to date the payment has still not been allocated to the account, instead its in activations fees which I have already paid. its frustrating to speak to people there as no-one can assist you, I have eventually emailed the Collections team leader 'Quanita' and she has also not reverted to me! I also don't get my sprint rewards which is ridiculous as I go to the gym often to qualify, so why have a rewards program if I have to call for my rewards and then I get passed around from Pillar to post. I cannot just forget about the money that I have paid! as its a monthly fee that I have paid, again I made a payment in October and its also not been allocated correctly! Please VA can you actually sort out this query or do your employees remain in competent? I am rather disappointed in the service and would definitely not recommend VA to anyone!
