R6360 was deducterd from my account

R6360 was deducted from my bank account without notifying me of it ,but the bad part of it all it's for a phone I don't even have and on top of that my account went in a overdrawn amount of R2500 that I just lost because of stupid people that cannot do their work ,so I just need to know who Is going to pay me the R2500 back into my account. My installment is only R400 per month.<br> The R400 was deducted and on the same day R6360 was deducted to this was on the 2March 2015 <br> I need my money back and I'm taking legal action against Telkom Mobile if this matter is not sorted out today. <br>
