Dissatisfied client of Vodacom

Ok so I take out a new contract with Vodacom and upon realizing that I won't be at home or work I inform them to deliver my parcel only from 18th of March an agreement was met n the agent said she'll make a note of it...... Bang Monday morning 11th March I get an sms from Ram that they delivering to my house address of which I had stated to the Vodacom agent to change my delivery address to my work address n that I'll only be available at work from 18th March onwards. I've been calling both Ram and Vodacom to deliver my parcel to my work address from last week Monday 11th March 2019 till today 20th March 2019 none of the Vodacom agents I spoke to so far ever sent communication to Ram to change my delivery address .Today it was delivered to my home address but now the problem was that the proof of residence is not in my name but I was never told it was supposed to be in my name n the the delivery person left with the parcel again. Vodacom is so far giving me a very ****py service and expecting to debit my bank account at the end of this month,their communication sucks cos people aren't doing their jobs.
