My email address *******ly taken away "***"

Telkom Sales staff at Cresta Centre removed my email address "***", when I migrated from ADSL to Wi-Fi in February 2020. I have been trying to get them to give me back my email address that has not been taken by anyone else. 1 Year and 2 months later i am still sitting without my email address, however that does not stop them from charging me for this. The staff are so ***********, not 1 of them are able to give me back my email address. (i have been liaising with more than 20 different staff members) How can they not get 1 simple task correct????????? This nightmare has cost me financially emotionally and mentally. Come on Telkom catch a wake up
