Terrible Service KFC online (Brackenhurst)

On the 5th of April I made an online order with R100. My order was canceled without anyone informing me. When I called to enquire I was informed that it was canceled because it's over 5km. The App indicated that the KFC is 3.7km away. I was told someone will contact me and I will be refunded. Almost two months have passed and this is not resolved. I have sent emails and messages on Twitter and I get an auto reply that someone will contact me. When I called again to enquire I get told I have to wait for up 72 hours for it to be resolved. I wonder if this SLA includes the 2 months I have waited. The lady just said it's the SLA and did not consider the fact that I have been waiting for 2 months without assistance. I understand KFC is a big company that makes billions. I am just a customer fighting for R100 that feeds my family. Clearly I don't matter. This is actually theft and I am very disappointed.
