Shocking customer service!!! NO EFFORT OF HELPING

I am absolutely disappointed at Truworths customer service given from the branch manager Linda Naicker. Firstly the online site is absolutely slow. I purchased items online that I needed to return. A friendly manager at bluff store assisted me as they didn't have stock of the items I needed and no longer have an account that I used to purchase my items. He then happily gave me a voucher. Little did I know that I cannot use a voucher as payment on the online site which is really pathetic as all the other retailers tiy can use vouchers as payment. I was sadly unable to reorder new items due to this. I had driven all the way to Galleria store to look for a specific takkie I needed. They had non of my sizes. I had then chosen a puma takkie and tried one leg on. Disappointingly came home and tried the other leg which was loose... Assuming stretched. I was so frustrated as I was loyal customer to truworths and always purchase items. I am in customer service field for 18 years and was disappointed at this outcome. I called the truworths Galleria branch and spoke to the manager grace who I had explained my situations well multiple situations that I had encountered to her . She unfortunately couldn't make any decision without approval of her branch manager. I had requested that they refund me for the shoe in cash so that I can buy it on the actual site itself as they don't have the shoe I want and the one I bought was clearly stretched. I had paid partial with gift card and partial cash. I called her at 9 am this morning. The branch manager was in a "meeting" from 9 am to 5 am. I called at 1300 grace called back advising she is still in a meeting. I called at 1700 grace advised that she just sms that she cannot refund a full cash value. If a customer is unhappy as you do not have stock of item they require, after been disappointed several times. And to not help. There are many ways of over riding rules to assist during customer service and there was clearly no effort here. I do not want the takkie and they refused to give me a cash refund. I do not want a voucher as truworths stock is very low with a very low variety of shoes and moreover after these experiences I wish to no longer shop there I will share my experience on the with social media platforms.
