I upgraded the 1 April 2021. On 6 April I cancelled the upgrade and gave the device back. Since then I struggle everyday that the amount on my account to be corrected. Now the wrong amount eas deducted from my account and still no one at Vodacom can help me as the answer is always WAIT. VODACOM CUSTOMER SERVICE IS PATHETIC they so easy to take your money and to upgrade but there it stops. No after service
