Severely unimpressed with service

For the last 2 weeks or so I've been trying to open a contract for a new phone with Telkom. Each time I go to the store there is a new issue. First they say okay everything is in order but because we have internet with them they must check our credit and they'll get back to us, which they didn't. We contacted them and were told there is an outstanding R200 to be paid. So we pay it and go in store again. Then the amount outstanding changes to R1000 (in the space of 3 days). After this issue has been sorted out we find out they haven't sent proof of payment to head office yet. They'll do it and we can pick the phone up in 2 days. We call 2 days later, nothing has been sent in yet. Seriously? I would just like to give you business that's all. I was hoping to get the deal for July but now it seems that it won't happen in time, in which case I will no longer be interested. While I understand that all of the above is necessary why can we not just be given all the information at the beginning and why can't people call us back and submit things that they are supposed to submit? I was hoping to get the deal for July but now it seems that it won't happen in time, in which case I will no longer be interested.
