Online order

I bought my kids snacks on their online portal on the 4th of August and estimated delivery it said 6th of August, delivery was not made nor the shift in my order when tracking it online, on the 7th called the store Edith Tefu answered the phone and transfered me 3 times but the phone kept getting cut when it got to the online store department, the forth time she gave me attitude and we had an argument then I asked for a manager she put me through to Florence Sibeko who promised to call me back after listening to my query and said he will let Edith's manager know about my problem with her, Florence called me back and put me through to Lesedi from the online department who said he will push for my order to be processed and delivered the following day which was on the 8th of August as the drivers leave at 12 midday, okay I was happy and willing to be patient for 1 more day, 3am I got an sms that they had to cancel some of the things I had ordered due to no stock, 9am on the 8th I called the store and they had me on hold for 2 hours then eventually Nancy answered and put me through to Lesedi who said the order is already out and he cannot do anything so he will put me through to Lesego who is the manager okay cool spoke to Lesego she said I must pay for the order again as the refund for he canceled order has already been processed and they had stock but still canceled Some of my things and I had to pay into the store account did an immediate payment as I also felt the urgency for her to process my order then she promised me delivery on the 9th of August, I called the store around 10 am when they opened she was busy and the Nancy promised to call me back once she has spoken to her and she did then put me through to Lesego she said she is processing it and I will receive same day, they knocked off and I didn't get my order today it's the 10th I don't know what to do as a client, I feel ****med by Makro suck a big store and all they can say is I'm sorry! I have been patient but honestly I am a very dissapointed and unsatisfied customer. The reason for online shopping and delivery is to save us time and money otherwise I could have just went to the store to buy if I was not going to enjoy the benefits of online service. Nancy Thank you for the service you gave me you must teach your colleagues customer service, I really appreciate it.
