Telkom upgrades department

Telkom upgrades department phones me constantly for upgrades, sometimes 3 times a day. Did upgrade on 6th of March 2023... it's now the 15th of March 2023. When i called them to find out when the upgrade will be delivered.... answer is no stock and they can't tell me when they will have stock. I should phone again on Monday to find out if stock has arrived. or I can wait till I get a SMS one day. CSN28752
