TFG Online bad service

I made an online purchase payment of R68.00 made and the rest of 62.00 was taken from my account ,only to receive an email that it has been cancelled,I'm told to place another order P*** and this one I must pay delivery fee of R50.00 still I obey I paid R118 plus R62.00 from my account as the previous order was cancelled, I get an amazing that this second order has been cancelled due to a technical error and I'm given a voucher of R100 ,I phone again to be told yes this order is cancelled I request my refund email bank statement again this time for R118.00 and I'm still waiting for my R68.00 ,since I want this item so bad im told I must place another order I do and use the voucher 2DAA7075c319531 and I pay R30.00 to balance the voucher with R30.00 to make R130 P*** Then on the 1/7/2019 order is cancelled again but order P*** gets invoiced ,I call TFG Online support Aghmad was polite understood my frustration but when I call and query R68.00 spoke to Saren who told me I'm Lying I never paid R68 which I have emailed my statement 4 days ago. I'm so frustrated angry and so disappointed on the treatment I have received,I wish I could just tell everyone about my bad experience from TFG yet I have nothing but loyal.
