Pathetic service from vodacom upgrades

***, I recently did an upgrade with vodacom online where I receive my phone quite promptly after using this phone for a week this phone became defective and I contacted online to have this phone collected so that a new device can be issued. the device was then collected and the upgrade was reversed however I am unable to upgrade and I need to wait for another month with no device being able to be used. I contacted online to request the upgrade date be changed so that I may proceed with my upgrade but this logged call was subsequently closed and only credits were passed onto my account for the initial device now I have no device to be used for the next three weeks as the upgrade could only be done on the 7th of August 2020 Checking the upgrade date on the vodacom system I find that the upgrade date is now 2022 I have not been contacted in the last week and a half by any representative of vodacom or upgrades department with vodacom and the reference number is now closed. This is pathetic service from vodacom
