Bad online service - Vodacom

I have called Vodacom online for a new contract for the Huawei 10 inch tablet for R199 per month for 24 months plus 5 gig data per month. I have an existing cellphone contract with them. I have been contacting Vodacom numerous times to follow up on the progress and finally received an sms today (20 April) from RAM to indicate that my parcel will be delivered at 1 Eden Towers, Palliser Street. I don't know where Vodacom got this address because it is not my home address and not my work address that I gave for delivery. I have contacted RAM to stop the delivery because the address is incorrect on the sms but RAM couldn't assist because Vodacom has to contact them with the correct address. I have contacted Vodacom once again to find out why did they give the incorrect address to RAM and the agent corrected the delivery address and told me that it was sent immediately to RAM. when I contacted RAM after 3 hours, Vodacom didn't contact them to give them the correct delivery address. Really it is so pathetic that I have to call hundreds of times and still be stuck at square 1 of my query.
