Vodacom employee not treating her job & customers with dignity

I app**** for a vodacom contract "Huawei P9" that was on special last Thursday I provided my confidential docs & signed vodacom docs. The lady promised to get back to me on Friday as the store didnt have stock then, to this day I haven't received a call from her. I went there today to find out what could have transpired, but her colleague gave her a call as she was on lunch she asked her colleague to ask me to leave she'll call me as soon as she comes back from lunch. It's now 19:00 I haven't received a call. My main concern is this lady seems to be failing to take me as a vodacom client serious. We give this ppl our proof of address & all confidential banking details, she seems to not even know where she placed my confidential documents, it's quite concerning to even think if the docs are not correctly used for it's purposes, how sure am I that my docs won't be used outside vodacom as there are syndicates going around in this times we live in hacking into our accounts or knowing where we live because they know how much we earn and exactly where we live as well as the day we get paid. 3. The special might be over whilst waiting in vain. I'm really disappointed in vodacom because firstly how do you even keep such irresponsible employees to represent such a reputable brand.
