Bad customer service

On 30/09/2021 a sales agent with the name Mariam if i remember correctly contacted me about a contract at telkom it wasn't the phone i originally wanted so she promoted the Huawei p40 lite, i told her it's for my fiance so i must first find out if he will be interested in that phone so she must call me back, she called back and i agreed on the p40lite we did the application over the phone but she was not professional at all she doesn't understand anything when i gave my adress i spelled out my address about 6/7 times but she got it wrong everytime she repeated to me.. We managed to finish with the application and she said someone will call and confirm my order. On 04/10/2021 someone called me to confirm the order and said the courier will inform me as soon as he picks up my package it can take up to 7-10 working days... On 12/10/2021 I called telkom to track my order and they couldn't track any order on my ID number said i must wait for this 14 days or so to pass to see if my phone will be delivered as it will only show on the system when the driver picks it up. 13/10/2021 my fiance received a phone call the person informed him that the Huawei p40 lite is out off stock/discontinued. I feel this is very very bad service because i asked for a Huawei p smart 2021 the sales agent informs me that it's out of stock so she promotes the p40 lite i agree with the p40 lite and TWO WEEKS AFTER MY APPLICATION WE RECEIVE A CALL TO INFORM US THE PHONE THAT WAS PROMOTED TO ME IS OUT OF STOCK. THAT'S Really bad customer service...
