Appalling Service Experience - Highly Disappointed

I cannot believe the service I have recently received from this so-called service provider! On March 30th, my family and I personally collected a router from their Queenswood branch. I specifically chose the black pattern skin for the router, heavily promoted in their marketing campaigns showcasing various color skins. Upon collection, the store assistant informed us that only red skins were available but assured us we could exchange it for a black one in a week when they restocked.

To my surprise, the assistant also mentioned the store didn't have a telephone, which is quite bizarre for a business. Nevertheless, I returned to the shop a few weeks later, only to be told they had discontinued the skins altogether. I then contacted Rain via Facebook Messenger, and they called me to arrange an exchange for the black skin I initially wanted. I was promised this would be done within 3-5 working days.

It has now been a week, and I have not received any follow-up call. When I contacted Rain again today, I was accused of lying. The unhelpful representative refused to provide a copy of the recorded phone call from May 17th, my order details indicating the skin color I requested, their name, or connect me with a senior manager.

I am utterly disgusted and concerned that this is a company anyone should consider doing business with. The lack of professionalism and disregard for customer satisfaction is shocking. I strongly advise against using their services.
