Utter Disappointment!!! Customer care need to up their standards

I am extremely disappointed with the service received from Vodacom taking into consideration i have 5 contracts with this service provider. I have called the customer care call centre more than 10 times from this morning, held on for probably more than an hour and i was cut off more than 5 times and no one bothered to return the call regardless of the fact that they were attending to my query. When we are charged incorrectly our service providers don't care about us especially in this trying time please be considerate. We are loyal customers and we don't deserve such treatment where not a single call centre agent can assist.
