Worst service ever

I placed an order 1 may 2020 at 16:20 on their app ,paid for the order online,2hours later I called to check what’s happening I was told to relax my order is on its way, they had a lot of orders, I waited until the store closed, tried to call but I had no luck. At 22:00 I received “please call me” on my phone from a number I didn’t know,few minutes later I received a call from that number saying I should come to the store tomorrow to sort out my order, 2 May I callled the call center at 11:00,I was told the store manager will call me back,but didn’t,I went to the store and asked the driver if I could speak to the manager about my order, he said I should wait outside ,15minutes later the driver comes out and say the manager says she is busy I must call the call center and sort out my problem with them
