Failure to deliver order or refund order

Purchased a new S26 on 3rd March 2026. The next day I attempted to cancel the order due to the incorrect colour chosen.

I contacted the Call centre for assistance to either swop the colour for blue or do a refund.

I has been over 30 days, and I have been calling the call centre often for an update. At first, I was promised a colour change and a week ago they promised a refund, I have not received my phone or go my money back to date. This is pathetic service from an internation company.
