Upgrading problems

No-one at Vodacom's cares to phone the customer. As you can see from my reports above, I am still battling to upgrade. So today my phone is deactivated, because my account is in arrears. My account is being paid by debit order (never miss a payment for more than 20 years) but the upgrade fee is already on my account. No response from Vodacom's, just sms's \ I must pay my account is". Nobody check the account to see what happened"
