Pathetic

In sep 2015 went into the store with my dad to upgraded the one line as my dad the account holder but it gets debited from my account. The consultanat mentioned there's a promo for early upgrade for my other line so we should come in december.Got there december told my dad which phone and the consultanat that helped didnt tell my dad the promo over he added a new line knowing my dad dosnt even know the difference. Went back in a day or two with a faulty phone and then only found out he never upgraded but added a new line. Phone got sent away and The Manager said when the obf is approved the line will be cancelled. We'll obf was approved but she never contacted me we had to phone after her the 29th december when we got hold of her she said she will be sending the forms for it to be canceled i dont need to worry. I was charged ever since for a phone i dont have and only in feb she cancelled the line and said everything sorted. Yet i was being billed one way and no credit. the 1 april R7219.25 was deducted from my account lord knows from where and the other line and my account. Now they saying it's for the line that was cancelled how the hell?This is not customer service.
