Horrible state of admin / accounts department - rather use another provider!

For 15 years Vodacom is debiting my credit card for the monthly balance of the contract. Beginning of this year the previous credit card expired and I called Vodacom many times to give the new card details, as their weblink does not work. After spending many calls and lots of time, finally someone called back to get my details and the then outstanding balance was debited from my new credit card. Yesterday I received a SMS telling me that the account would be in areas again and when I tried to call Vodacom, the agent said there is no note in the system about my card and put the phone down. Seriously Vodacom, after paying each month on time for 15 years by credit card debit order, you should be able to do much better! Please sort out your system and just continue with the payment method as always before. Please get back to me and sort above out within 24 hours, as otherwise I might not do the upgrade that is due and change to another provider that has is's admin in order!
