Poor and Unprofessional service from Fuel attendant and Customer Service helpdesk

I recently downloaded the Astron Energy app yesterday (19.06.25) and then today it was my first time to use the above company. After pouring fuel, I got a voucher from Astron to use. I then decided let me go put fuel again and also redeem my voucher. Got to the Astron Energy service station corner Main Road and 8th Ave Walmer Port Elizabeth. I then asked the petrol attendant (Luyolo) that I have a voucher and I want to redeem it. Please help since it's my first time and he said I can redeem in the store or can redeem it on fuel. I then said he can use it on my fuel bill. After done putting fuel, he then tried to redeem the voucher and it was declaring saying it's been used already. He tried 3 times but it was coming with the same error. I then asked for a manager or supervisor only to be told that they have left the garage at 3pm and it was around past 4. I decided to call Astron Energy customer helpline and spoke to this lady called Talita or something similar to that, she asked for the voucher number and i told her that I can't access my app since I'm on the line with u. She then told me that I must phone her back when I have the voucher number and then told her I can't phone her back coz I don't have enough airtime. She told me that she will me back after 1 min. I waited and waited and waited almost for 30 mins mind you I have on shift at work and being struck at the station. Decided to phone back and spoke to Lelo who eventually called me back and tired by her best to assist even thou she couldn't help coz the voucher was to buy in the store not fuel.

It was my first and last time using Astron Energy again. The service I got from both the fuel attendant (Luyolo) and the customer service lady (Talita) was totally BAD 😞 and unprofessional.
