Disappointed in TFG

I am honestly so disappointed with TFG's online services. I ordered an item online on 31 August 2020 and on 6 September 2020 I received an sms to say that my parcel is on its way to the requested mall. Only for me to follow up a few weeks later to be told that my order had to canceled due to an over sell of product on the website. I did a split payment with E-vouchers and paid the difference via eft. My eft refund was done but I am still waiting for my E-voucher refund. It's been more than two weeks now and I still have not heard or received anything from TFG. So disappointing and disgusted by their services!
