WILL NOT GET ASSIST

On 21/03/16 I went to Telkom Mobile Riverside Mall to do my upgrade. I did not get the name of the consultant that assisted me as he did not wear a name badge. He advised me that my contract was due and that I should come back within 3 days, I was advised that the store was closed on 25/03/16 as it was a public holiday and that I should come in on the 26/03/16. On 26/03/16 I went to Telkom Mobile @ Ilanga Mall but they advised me that they were out of stock on the Samsung TAB E, they told me they could process my upgrade and they would contact me to collect my tablet once they received stock, I was in a hurry to get the tablet so they advised me to try Riverside Mall. I tried on numerous occasions to reach Riverside there was no answer. I then went to Riverside Mall, got into the store and it was empty there were 2 consultants behind the counter, I then explained that I was there to do my upgrade & they told me they out of stock i then asked her process my upgrade and i would collect once they had stock she rudely rep**** that she was not prepared to get fired on my behalf. Is this how Telkom treats customers? Like we are *********? is being rude acceptable?this is disgusting.
