Unhappy

I initially signed up on line for the Huawei P30 pro because I didn't see the P30, but I didn't qualify for it so I was offered the P30 lite I received the quotation invoice and I see that it's for 36 months instead of the 24 months I wanted. I've been given the runaround for the past +-5 days trying to resolve this, now the package is on it's way but the plan is wrong so can someone please change it to the online offer that you have of R279 for 24months. Can someone please call me asap
