Patient wearing thin

It's been 2 months two weeks since we payed for the Wi-Fi from SADV vumatel,the person who helped us opened an account for us was quick to help and sent a reference for us to pay but no service delivery. We've enquired alot of times and they've been telling us about the wrong address and we've been trying to rectify that but they give us empty promises. People who app**** after us had installation crew come and install for them with no problem at all. 2 weeks I called the call center and the guy I talked to said he'll lodge a claim for me and gave me some kind of reference number but not for payment. Even today when they call we are asked about the address issue they usually ask about. Is it that hard for them to rectify the mistake and come and install for us? The guy who opened the account for us is even impatient and is not following up on the issue
