Vodacom charging legal fees without notice on account

I had made payment arrangements with the Vodacom legal team a few months ago and was making payments for an amount in arrears on my account. On 26th September my account was handover to a legal company MBD. I was not informed of this handover or why the account was being handed over to them. In addition I found today an amount of R211 was added as legal fees. I was not informed of such a fee being charged. I have one final payment to make to settle the account, so this is in very bad taste that I am not informed of the account handover and also being charged legal fees. I require someone from Vodacom legal to address this issue and reverse the fees as it's one more amount required to settle the account.
