VERY Disappointed

Most pathetic service ever! Have been a Vodacom customer for more than 12 years and this is my first time that I have to go to the extreme, for solutions. Upgraded one of my numbers in May 2023. Was still billed for the old handset, that has been paid in full. Eventually received the credit notes, and well well to my surprise.... DEVICE RELEASE INVOICE for the old handset in December was received. Numerous calls has been made to Vodacom and problem still not solved after nearly 8 months later. Furthermore, they simply refuse to give you the contact number for the accounts department. ****** ridiculous!!
