Very poor service

I purchased a Sinotec 55" TV with a free Sinotec 2.1 CH soundbar on promotion at R5999 online. I spoke to 3 people from the relevant department to assist me with the purchase online. I made the purchase successfully. I received notification to collect with TV within 7 days. I went to collect my items today and I was only given my TV and they refused to give me my sound bar. I refused to accept that and then after making me wait for 40 mins the manager tells me that we should go to the return queue and wait for about 20 mins, they will cancel the existing order and do a new one with the TV and sound bar. I get to this queue and wait another 45 mins only to be told there is no stock of the sound bar and they might get stock in 2 weeks. When I purchased online I added my TV license details and this approved and accepted but in the store I had to wait another 30 mins for finalising the TV license. I am lost for words. This has been a complete nightmare and waste of time not forgetting I purchased online to avoid making contact with people due to Covid19 but this all process has actually made me come into contact with more people. You have let me down Makro and this has left a very sour taste in mouth. Your customer service is very poor, your online website needs to be user friendly and more accomadating to the elderly. You advertise promotions but can't train your employees on how to help your customers buy online or how to answer questions accordingly. On the first attempt to collect my TV today, I was not asked about TV license and neither was the TV tested but after the above events transpired Instore they want to know test the unit and obviously this took another 10mins. I spoke to Shaun (a manager) and requested for him to make a note on my invoice that in 2 weeks I can come and collect the sound bar and this is at no additional cost. I also requested for an email from the store manager Thandiwe confirming that they have no stock of the sound bar and that when stock arrives in 2weeks they will notify me to collect at no cost. I am awaiting that email.
