horrible service levels

I have 3 contracts with Vodacom and I have always upgraded at this store. I called in a week ago to enquire about an upgrade that is currently due just like I have been doing for years now. I was brushed off and told to call the customer care. I then decided to personally visit the store. on arrival at the store I was the only customer there at that time. I requested seeing one the salesman to forward my queries. there were two salesman in plain sight talking amongst each other and when approached by the ticket lady the gentleman did not even care that I was waiting. he just kept asking the lady as to what I wanted. she obviously did not have the access and expertise to help me. as proper customer service he needed to get off his chair and enquire himself as to what I wanted and not just laugh it off. that is extremely unprofessional from a company that is predominately service driven. I am definitely not upgrading at this point in time.
