Extremely Unsatisfied

I booked my phone in for repairs on the 10th of November, by the 12th they informed me on how much the repair would be and I paid on the 14th , I've been trying to do follow ups on the repair and no one knows what is going on, the vodacom app still shows today that I need to either accept or decline the quote , but I was in store and paid. I tried calling yesterday cause I am not getting any feedback on if they have started if they have finished so I am really getting frustrated in regards to this. I feel like the only other thing is to complain because I am just not getting anywhere , I was in the store where I booked my phone in and they had told me that the confirmation email of payment never went through to workshop , so had I not called on my own and tried figuring out the situation no one would have noticed that the email was not sent.
