In my honest opinion, a reliable customer service is one reason why I would chose company A over B. Ignoring customer emails because of internal politics, product uncertainty, partnership issues, does not help to alleviate customer anxiety and can result in lost of trust towards said company. If this is not remedied, over time, the company can lose its face and all the good image they have worked so hard to build up. I for one can say, that for anything this expensive, it is my expectation that publicly listed email address or a web form, someone would contact me back within a couple of business days. It is clear that they are aware of this issue, but choosing not to comment. It does not really matter whose fault it is, or who caused the issue (Tidal deprecating old APIs, or choosing not to support old Android), it is not Tidal who sold you the device, it is A&K, and they should respect you as a customer and at least reply to your emails. I am saddened this is happening and feel for all of you in this situation, it is not right.
