Upgrade Issues

Every time I am due for an upgrade with Telkom Mobile there is an issue on my account ! The latest is I upgraded my account to a new device on 11 March 2016 and then in August of 2018 I took out a new contract and put my existing contracts onto my business name so the system automatically took this NEW date as my upgrade and pushed forward my upgrade date on the old contract simply because I changed the billing details ! The consultant on the phone kept me on hold for over an hour before I put the phone down and this after telling me that there is a 72 WORKING HOUR turnaround time, not 3 days but 7 working days !!! so now I cannot upgrade my account to a new device because once again Telkom has ******ed up the account.
