Device missing for 4 months .

Huawei was running a promotion for free screen repair for P-Smart 2019 phone which I was one of 10 000 customer for receive the free repair screen for my phone , that was in January 2020 when I got the email from Huawei VIP technologia group. The courier company came to pick up my phone on the 13 February 2020 with ref no.COL***6. On the 18 February they sent me an email saying the device I sent was not a P Smart but a CairoGo-L02, I emailed back to say that I sent the right device because before they approve the Promo I had to sent proof of purchase for the device to say that I own the device which I did . Few day later the lady Charlize Braz from technonogia group called me to tell me that the device they received was not a P Smart were I told her that they need to do an investigation with the courier company. On the 05 March 2020 Charline Braz sent me an email to say that they got my device as it was mixed up by the courier company and they will dispatch on the same day. Three months past with no email, no phone call or my device delivered back to me. I called the HuaweiVIP technologia group the calls are not being pick up. On the 11 May I sent an email to Charline Braz to ask what’s going on I was not given a straight answer as she was still waiting for my device from the courier company which is not what to told me 3 month earlier. So I am very disappointed with Huawei as they not even doing anything about this as they promised to fix my device, I called their call centre about 4 times spoke to different people who gave me hope but not not sure why my case was not dealt with. I spoke to Priska who was the one that communicated with Charline Braz to find out what was happening and she told me that Charline Braz is dealing with my case and they have found my device and was sent to the wrong shop . Even today I don’t have my device no communication from Charline or an email from her. I feel that I am being taken as a fool since I’m calm . I need assistance urgently it’s now July and I still don’t have my device. I want my device back .
