Unprofessional help

I have a LTE CPE B593 Huawei wireless router on number *** and since last week I want to change the password. But I cannot for no aparent reason. So I tried to register on MyTelkom, but it keeps sayng : according to our records, someone attemted to use your email address to register however only ONE email address can be used! I have had this Telkom wireless router since 2014 and have never registered!!! So I phoned and either am directed to another number or they pick up and do not talk to me, you can hear them chatting to one another. Today I wasted R110,00 trying to register and change my password but there is no one at Telkom who can assist me. So here I am R110,00 poorer due to very poor unprofessional service and still no where. I hope somebody in Telkom reads this.
