Bad experience from MTN and Samsung

I pre booked my S9+ in March so that I could get the fitness device. Do to errors outside of my control I have been trying to get the device. (MTN not upgrading the system for VAT). I have been on the phone, visiting and emailing the store and have got no positive response in this matter. I would not have taken this phone if I was not going to get the fitness device.

I had done everything that I was told to do. MTN both the store and headoffice says they are trying to sort out the issue
