Sheer incompetence

I had an excellent experience with Vodacom to do my upgrade my account, however after numerous calls to confirm to delivery address and details, they firstly spelled the address wrong and used my mobile router's number as contact number, this is after I repeatedly mentioned that it is for the number I am calling from, the number that I am upgrading....It has now resulted in the courier not being able to reach me as my router cannot take calls, I feel this is poor service, why does a agent call me 2 times to confirm my address and contact details if they still cannot manage to rely this correctly to the courier company. I now can only get my new phone and contract sometime next week, this is sheer incompetence and makes me wonder if I should even proceed with this deal....Vodacom please assist to get this thing sorted out
