Account suspended

Tried to make a call today only to find out Vodacom has suspended my account. After being on hold for 20 minutes I decided to try the customer service number, the lady told me my account was suspended but it said on the system I an up to date as I have been every month for the last 8 years. She unlocked my account and put me through to the accounts department so I could get feedback, this number is never answered and I eventually gave up after another 20 minutes. <br> This is extremely unacceptable and I would appreciate some feedback.
