Missing Parts

Hi booked my Nespresso machine in for repairs at the Sandton shop. I paid them for the repairs the same day. I gave them a complete machine and they said they will send to me when fixed. I receive the machine 4 days later incomplete. I had to phone them several times to get my parts back. they agreed. But now do I battle to get the correct parts and Refilwe is not getting back to me. I have to phone them every time and I have to drive to the branch to collect the parts. This is really not what I will expect of a company like Nespresso.
