Yassir a lot of useless

The first time I used the service was on 20th Jan 23. The worst experience in my life using any delivery app or provider. I placed my order around 5:20pm , i was called around 5:45pm by the most obnoxious and rude employee of Yassir. The person who is known as Tawanda and a supervisor went on a rant first stating that he had personally canceled my order because he knows that i am abusing the code that allows you to get money off your first purchase and that i am abusing the goodwill of the business. He continued to go on and on berating my character and making assumptions. I escalated the matter to the Yassir customer department, i was contacted by a consultant Nonza Giwu who said that the person Tawanda was a supervisor and acted out of his mandate and authority by calling me using his personal cellphone. She said that she would escalate the issue to management and my money would be refunded. She also assured me that i would get to speak to management on the 23rd Jan 23. I have had no reply since then, my money has not been refunded. Also there is now no trace of the order or the cancelation thereof on my app. The most appalling service ever. I would rather go in store and purchase products rather than having my character maligned by Yassir and its employees. You definitely get a zero for customer service.
