Lack of Morals and common Customer Service

I saw a special on the Sportsmans Warehouse for 30% off Sports Tech (Yellow Ticket Sale) and tried to order online but only to realise that the Promo is instore only. 11 May 2020 i visit the Gateway store to be told that there is only 1 instore that is reserved by a customer that had called and reserved the stock. i then asked which other store does have stock in reasonable area due to travel restrictions of Covid19. The sales lady checked their system and located 1 available in the Ballito store. I asked to confirm if it is available for purchase so i could travel to purchase. They tried for 15 min to no avail to contact the store. They then proceeded to call the Manager of the store only to be told that the Stock had been reserved for another customer to collect. I then took this matter up with the store manager of the Gateway store, who then said unfortunately this is their process to reserve stock for phone in customers. I argued the point that if the sale is instore it should be sold to customers that are physically instore at the time of the stock being available. After no help at store level i decided to call the customer complaints line. What a disaster to think that they would assist. The first called made was answered by a lady representative who do not identify themselves by name, She did listen to my query and asked me to hold on as she checked up for me. After being on the line for 12 minutes i was cut off. I decided to call again, this time after waiting 9 minutes and 45 seconds i was answered and immediately cut off. the Third call was answered by a lady named Weiner(not sure of exact spelling) who took down my query and my contact details. She said she will query this matter with store revert to me, however i have not had a reply or any correspondence from anyone as yet. Is this how Sportsmans Warehouse treats its Loyal Customers. WHY ADVERTISE A SPECIAL IF IT IS NOT AVAILABLE.If there is such an option for customers to call in and reserve products then why not advertise it to the patrons of your store so we also could have taken advantage of this service. We would not risk going through numerous road blocks and risking our health during this pandemic to get to a store to make a purchase. The product that i was interested in purchasing was a Huawei GT Headphone bundle for R2499.
