Not so incredible with refunds order #***

I placed an online order for a printer 12 May 2020 as I need the printer to assist the children with school work. I was advised on 2 June 2020 that they don't have the particular in stock and that the store will request a refund of R899 to my credit card. Since then someone would call me weekly to ask if the refund was received. I have been requesting them to include me in the emails they send to head office to request my refund to no avail. I have been calling the call centre with no luck also been emailing them at *** and *** with no response. I have requested my bank to assist and they can't because incredible connection has not issued me the credit note that I have been asking for for the pass 3 weeks now. Needless to say I don't have the printer and also no money. I can't go and buy another printer because I am waiting for me refunds. I am irritated and frustrated to say the least and will never order from them ever again they call me weekly to lie to frustrate me and they do not keep by there promises.
