Terrible customer service

On the 14th of October I purchased airtime from our local store. They are a airtime vendor for Flash eezi airtime and you can recharge with their vouchers on any network. After loading the airtime I received a confirmation sms that the airtime request was received. I noticed that I didnt get any sms confirmation from my service provider for the amount. Checked my balance and it wasnt updated yet. So I waited another 30mins and nothing. After phoning the flash call centre and following their instructions my balance was still the same. After this I have been in contact with Sandiso at the call centre almost daily. On the 23rd of October Sandiso sent me an email saying I can go back to the vendor and get either a refund or a replacement voucher. I proceeded to ask him if he had arrange this with the vendor cause there would be no point in me going there with this story if Flash didnt arrange it with them. Flash was not able to get hold of the vendor so I opted to go there and then make contact with Flash so they can talk to them from my phone. I did this & explained all to the vendor, I contacted Flash and was put on hold for almost 15mins and left the store still no airtime and no contact with Flash. I got the number for the vendor and sent it to Sandiso so no more excuses of not being able to get hold of the vendor. Since then I have been messaging them every day asking if they had made arrangements with the vendor for me to collect my airtime and every message gets read with no response. After loosing my chickens yesterday I got the following response: "Hi, we still waiting on feedback, we will inform you once we have feedback." All they have to do is call the vendor, refund him and he refunds me. So please tell me, feedback from who and for what purpose??This is the worst customer service I have ever experienced. They are not bothered with sorting out my issue or apologising for the time it is taking. The replies I got from them via messenger has been so never minded and uninterested in me as a customer. I will definitely not be supporting them anymore.
