DISAPPOINTED!!!

I am so disappointed by the service I received at KFC (Commercial road) in Port Elizabeth. On Saturday evening we had a voucher from Old mutual valued at R150, we decided we'll order the food online and just collect it at the drive thru. I ordered from the exclusively online deals for meals valued at R265, entered the voucher at the checkout and it went thru, I processed with paying the remaining balance with my card. I entered everything and I received an sms after that that the balance has been paid from my account, while that sms came thru the online services just stopped working stating that something went wrong, took me to the bucket section stating "your bucket is empty" so I thought to myself that it'll refund me in a few minutes if it didn't go thru because I've dealt with online services and I know refunds aren't even 5 minutes and they'll reflect back to your account. We waited for about an hour for the refund but nothing came thru which means the order went thru (In my head). We drove to the KFC, stayed there for like an hour or 2 trying to get our food because the money has gone thru but apparently they can't see it on their system so they can't give us the food without a confirmation from their side. My phone even died in this whole process. I was then given this other guy's number (I don't know whether he's the manager or what) and I'm told to leave and contact this guy. I get home charge my phone and after about an hour I call this guy. He tells me that he can only help me tomorrow (Sunday) because he is not at work, that I should send him the screenshot of the money going out of my account. I proceed in doing so and I also send him the voucher code that was used (bare in mind the voucher code now states that it is invalid which means it has been used). On Sunday he was silent the whole day with no update whatsoever, I contacted asking him asking him what's going on and he said he'll call me on Monday. Monday has now passed and I'm starting to get ****ed off because this guy clearly doesn't care! Today, I received a call from the guy saying he thinks I selected the wrong KFC but I am certain I didn't because I double checked multiple of times, this call happened before 8 am this morning and I still haven't gotten an update from him.
