My decorder

On the 15th of Jan I got an error on my decoda - E30-0 and I tried all the platforms, WhatsApp and calling to remove the errors... The error was not removed, I then sent an email on the 18 and I got an email back later that day to say that I was unavailable but no one called me... Then sent another email and was called around 7 and the lady said she will send an email on what to do which I did and it still didn't help... Then sent another email on the 22nd and then I was called on the24 around 7 and the guy said he was going to call me the next day... No calls ...No decorda ... Nothing ...what is happening coz I only bought my decoda in Aug 2020 but iv got this error ... This is ****en bull **** ... How can it not be fixed n they told me I must buy a new one ... For what reason ... I didn't add the error ...I want a new decorda otherwise I will keep on writing here about how useless ur agents are ... Are u guys selling Chinese decoders ... How can you tell me that but iv got family members who have had there for over 5 years and nothing is wrong with there's... This is really unacceptable
