Telkom Staff has no idea what they are doing

Prakash bridgelall did an upgrade on is telkom internet package to uncapped 10mb. Then asked me for assistance as his emails no longer worked. Found out that the mailboxes dont exist, so i called telkom. they stated mailboxes where all deleted because of upgrade. THIS WAS NEVER STATED TO CLIENT!!! Asked what can be done, Tech support said i need to speak to Sales, find out what happend asn ask them to reactivate the mailboxes. Called Sales they said all mailboxes are fine, speak to tech support for passwords. Called Tech they say cant do anything sales needs to activate!!! I cannot get anywhere with this!!!! Just going in circles
