Email address setup/Incorrectly spelt and without confirming with me

I took a new uncapped package with Telkom for R599pm which comes with a free email address,however I was not asked what email address I required and an email was set up for me that was incorrectly spelt using my name and surname that was spelt wrong.I called in to Telkom and was advised that Sales can assist me in changing the email however the lady I spoke to refused and said that she can not change it and cut the call on me.

I would think that the customer has the right to choose his own email address as I know.Please could this be dealt with as the email address that has been setup frustrates me as my surname is spelt wrong and is humiliating.

I would like to be contacted and the email address changed to the email address I want.
