Sinotec Technical Support Ignoring Follow-Ups for Over 15 Days

I have been a happy Sinotec TV owner for the past few years and have always been satisfied with the product, which makes this experience even more disappointing.

Recently, the DSTV app on my Sinotec TV (Model: STL-55U20AT) stopped working and now displays the following error message:

“Unsupported Device. Please ensure that you are using a Google certified device and that your device is not running a modified version of Android.”

I contacted Sinotec support telephonically and was referred to technical support. I was then assisted by Vincent Lottering from technical support, who requested certain information via email so that troubleshooting steps could be sent to me.

I promptly provided all the requested information.

After hearing nothing further, I followed up with Vincent and was informed that the troubleshooting steps had already been sent. I searched my inbox, junk, and spam folders thoroughly, but never received anything.

I immediately informed Vincent that I had not received the email and requested that it be resent.

Since then, I have followed up a further five times and, to date, I have still received no response.

It has now been more than 15 days without resolution, without receiving the promised troubleshooting steps, and without proper communication.

What is most frustrating is not only the unresolved issue, but the complete lack of follow-up and customer care despite my repeated attempts to resolve the matter.

I have always supported the Sinotec brand and have been happy with the TV itself, but this after-sales support experience has been extremely disappointing.

I would appreciate urgent intervention from management or the relevant support team to resolve this issue as soon as possible.
