Extreeeeemly bad service

With GREAT DISGUST!!!!!!!!!!!!!!! I did do an upgrade on the 14.10.2022 wrong address was logged by upgrade consultant. Tried changing the address and contact number on the 17.10.2022 first the consultants hung up the phone or **** and said changes have been done. After calling RAM Couriers nothing have been done on their side. Called back every day 3 to 4 times to speak to a manger. They said the manager is in a meeting called back again and ask for manager just to find out that the manager was never in a meeting. Called back again today to speak to manager and they said he is busy in meeting. I said I will hold on till I speak to a manger then all of a sudden he is not in a meeting. Now I spoke to a manger by the name Sindile he is saying " how must he resolve this?" The problem was not on my side due to LIES and consultants not doing their jobs the problem is mine now...........NEVER HAVE I RECEIVED SUCH BAD AFTER SALE. They where quick and fast to do the upgrade. I want a solution today or can I have someone higher in charge contact details thank you!
