Pathetic service

My whole experience started with Telkom on 13 March 2018 when I app**** for a Samsung S8 at the Menlyn store. They did not have stock, so they ordered the phone for me and I was told that it will take 1-2 weeks. I phoned at least 3 times a week (had to hold on for about 10 minutes each time to speak to someone) to follow up on whether or not my account has been approved and if they have received stock. They never once phoned me back or gave me an update. I have also been to the store afterwards to find out if there has been any updates, the one time they were also offline? Then, last week (7 April) I was tired of waiting for the Menlyn store, so i went to the Kolonnade store where I ordered the Samsung A8 (more readily available). Firstly, they were suppose to be open and ready by 9 o'clock, but the manager only pitched up at 9:05 to open up the store. Then, I received very good service from a newly trained lady - i can not complain about the way she assisted me. She told me that the the credit department will approve it within 24-48 working hours, which they did - sort of. A guy from head office gave me a call (Monday 9 April) to confirm which of the two phones (S8 or A8) I want , i said the A8 (the latest order). He then said that he is approving the account for the A8 then, and that i can go to the store to collect the phone. So that afternoon I left work a bit earlier to get the phone - when i got there, the guy from head office deleted both orders. So the same lady from earlier had to submit a new order, which was approved late Tuesday afternoon. She then told me that she will put the phone aside and carry on with the order, so when I'm ready I can just collect the phone. Today, i took time off from work to get the phone, but surprise surprise - I left empty handed again! The phone she set aside for me, was given out to another client by someone else. So now I told her that they must deliver the phone to me as soon as they receive stock, I will not be going into store again. I do not work or live close to any Telkom stores, so it is a mission every time. I have wasted so much time and airtime on Telkom. I have tried to communicate with Telkom via phone, email, online chat (on their website), Facebook messenger and I have had no luck with proper service, or even just answers!
