Wrong phone received

They called me for a special they have on a Huawei and a Samsung. I chose the Samsung and requested the 128gb Samsung galaxy A14 and not the 64gb. The agent said he has changed it to the 128gb. I confirmed this with him more than once and with his supervisor. Then they have an added service that helps to to set up your phone etc for R199 pm, to which I said no many times (the agent and his supervisor). I got a dibi mandate request for these services, so I had to call the call center to cancel it. Today I received the phone which is the 64gb. When I call the call center they rudely say no that is not part of the special, but they will listen to the recordings which will take up to 7 to 10 working days. They are quick to sign you up to make a sale but then they mess it up and I have to sit with the issues. This is unacceptable
