BIS Charged since I upgraded in 2014

I still dont know what cellc is going to do with my query. Their last update on my Hello Peter complaint was that their agent maropeng advised that he resolved my query, of which he didnt, to date i still ahvent heard anything from cellc. Paid for BIS since 2014 after I upgraded from a blackberry phone so a Samsung S4 Mini. Was only advised when I asked for a breakdown for my January debit order. So basically cellc lets their clients pay for services they dont use and when they finally realise, cellc just ignores their clients complaints. A total *******!!!
