HANDED OVER WITH NO CALLS

I closed my account in September 2014 and moved over seas.<br> <br> I arrived back in January and have this month received a phone call - THE FIRST!! that Multichoice have handed me over for R300.<br> <br> Multichoice NEVER emailed me to advise I had an outstanding account, NEVER called me on my Cell - which I still had in my possession.<br> <br> What is wrong with this picture, where suppliers think that it is ok not to call their customers first before handing over to Debt Collectors?<br> <br> Try picking up the phone, when you have a query on my account, you are quick to switch the service off due to lack of payment but you cannot pick up the phone to query if I have received an account from yourselves? If my account was closed and I have been on debit order - how can I be in arrears? I still have the same bank account number.<br>
