Makro refund

I ordered 2 Mobicel IXPRO 64GB Dual Sim for R 55.02 each and I payed R50 for delivery then Makro cancelled the order due to technical pricing issues or glitch . They sent me an email on the 27th of may that they will refund me in 48 hours then they changed to maybe after 7- 10 working days. On the 30th of May they said they sent my refund but it took days for me to receive it until yesterday on Sunday, on the 2nd of June They gave me R50 refund out of the R160 that I paid and a R50 voucher that I don't even intend to use ever because of the bad experience I had with Makro , I'm not only speaking about myself , including all the people who lost their money due to Makro technical pricing glitch so I feel like you used this pricing glitch to **** us since you sent me R50 out of the amount that I paid, you should stop online purchases because you have too many bad reviews already , I think it's better to purchase in-store . Plz fix this and send my full amount immediately I need my money
