Debit Order

I had DSTV decorder with multi choice which I subscribe debit order every month,recently I'm experiencing a problem with billing department, 25th October they didn't debit my account and when I asked why No one answered to me,they said they will come back to me and they disconnect my service,end of November they debit double,December I phone them on the 28th to check if the debitborder run they said they did debit on the 25th which it was Christmas and they told me not to worry,today the 4th when I wake up the service it has been suspended and I phoned to ask why,I spoke to Modiehi she said debit order reverse and she asked to hold on she hang up the line,I phone back I spoke to Yoliswa she told me that debit order was sent to my account 3 days before the 25th and I get paid on the 23rd and I'm surprised why they said there was no money as I had money on my account until the 29th and I asked to speak to the superior,she transfer me to Sakhumuzi he said hello before I tell him my story he hang up the phone,please assist as my service has been suspended.
