Pay back my money

I have been going up and down to Telkom stores requesting I get paid back the deposit of R 700 after cancelling my line after 3 months. It has been over 20 working days and I am still unable to get my money back.<br> How much longer am I supposed to wait to get my money back? Or should I do to get my money back????<br> Telkom is pathetic and I will never do business with you or allow anyone I know to use your services.<br> <br>
