Sound System promblem

<p>The Subwoofer was given in for repairs to Makro, since it was not working properly. The supplier checked it and returned it back saying everything is in order, than Makro requested that we should submit the unit as well. We gave it and then it came back saying we didn’t connect it correctly ( Everything is working fine) and they didn’t return the power cable for the unit, so we connected it as per instruction given. The sound system still had the same problem and now we also noted that the unit as the error message “ Power safe Mode” and then switched off. We send it again so Makro says the entire board of the unit needs to be replaced and no feedback on the subwoofer. This sound system is less than 4 months old and it is taking over two months to resolve this problem and Makro is not responding to us.</p>
