service sucks

On 24/07/2020 I upgraded 2 of my nrs. After I received the phones, I went to a vodashop, bought a cover and screenprotector. i realized that theconsultant upgraded the 1 wrong nr of mine. I contacted vodacom to rectify the problem. Now they need to collect the phone to cancel the upgrade. Nobody want to take responsibility for my costs to replase the screenprotector on the new phone. I am waitng now for 3 weeks for upgrade department's teamleader to phone me. Even after several mesages that I left and prommises that they will call me. Their service sucks. I am a paying customer for almost 12 years.
