ETR PERFORMANCE

i took my motorcycle for a suspension service on 18/12/2018 .I recieved my bike on 21/12/2108 and they damage my paintwork on my front mudguard and put blue insollation tape over it to cover the damage without telling me nothing.My motorcycle was resprayed just a month before, and it cost me over R 100000 to spray it.I am very upset about this,they offer to fix it but is not the point they just kept quiet about the damage
