I would give you no stars if I could. I spoke with rep and told him I needed a battery delivered and installed because I needed a memory saver used on my vehicle, he acknowledged they had them and it would be brought to my location with the battery. So 3 1/2 hours late the installer shows up to install battery , he has no memory saver says there is nothing on the work order about it. He calls his rep they say hook a battery jumper to my terminals I say if it blows up my ECM will they put that in writing they will fix my vehicle. He says no I refuse the service then they still bill me 449 dollars for battery service. I call they say maybe we will take it off but we will charge you $99 for service call nope so now I put in a complaint with my cc company! No no no no do not use this company no service no customer relations
