Worst ever service experience of my life

on the 11/09/18 I went to JetMart Dobsonville to make a payment on my Mother's account and received the worst service experience of my life (to-date).

When I got to the till area there were 4 people manning the tills, I went to the 1st nearest to me, advised the lady that I was there to make a payment and she rudely shrroged me off to the next till, no explanation just a "NO, I can't help you" then she left the station.

I then went onto a line were there was 3 staff members manning the tills, 2 of the attendants left their tills after serving the people they were with.

Spent over 10min in the line before I asked for the manager, a security person (Mawande) directed me to a gentleman in the store and when I called out to that person I found out that he wasn't the manager.

When I finally got to the till the attendant (Ntokozo) advised that my instalment due was R1139.05, I told her that that amount higher that what I was used to paying and she insisted it was the amount due, I couldn't pay the entire amount due as I was used to paying around R550 - 650 but decided to pay as much as I could so I payed R1K, when she gave me my receipt I found out that I could have payed R619.78. (as I was expecting).

Requested the manager once more and he was still no-where to be found. Requested complaints e-mail from other staff and got told there was no such, advised I could call, requested telephone line to make call, waited about 10min for phone as there was another customer on the line.

Manager (Siya) walks up to me as I was about to dial their complaints dept. tells me I can talk to him about the situation advised him I would talk to him after I made my call to complaints dept. manager took phone away from me and rudely advised his staff not to allow me use of the in-store phone.

Spent R35 to purchase airtime and call complaints dept were I was put on mute then hung-up on, called again and requested manager, spoke to complaints manager and got hung-up on again, had to call 3rd time to request manager to call me back. Advised I would receive a callback regarding my complaint in 48hrs (recieved callback on 17/09/18 from a totally different person who advised my problem had to be referred to another dept. that's when I hung up on what I feel has been the worst ever service experience of my life.
