Numerous attempts to get upgrade

This is a copy of a letter sent to supplier to which they have not bothered to respond!<br> <br> Since the inception of this agreement, I have been experiencing some difficulties with this account.<br> Whenever I call to do any form of enquiry, I am always advised that this line has been suspended, and that is always not possible.I have a debit order that religiously goes through on a monthly basis as well as a bank statement to prove the fact, when I mention this, I am then assured that it's a mistake on your part.<br> That is not want to hear at any given time, I am tired of hearing this, please do rectify this matter.<br> Secondly, I visited a Telkom store on 26 October 2015 , enquiring about upgrading my handset and was made to fill out all paperwork, three days later someone called me and advised that unfortunately they cannot proceed with the application , as my line has been suspended. I immediately called the call centre to ask them to please rectify this and was advised just to go back to the store and explain to them that this simply was not possible, given the fact that I am actually using the \suspended "line to call them"
