My vehicle began to vibrate & make rattling noises after I had a battery installed by a 1-800-Battery technician. I reported these issues to 1-800-Battery the next day after I had driven my vehicle & noticed that a push rivet was missing from the battery containment area. I was told a technician would come back out the next day to check on the battery. No one came out the next day or bothered to call me to reschedule. The following day I called again & spoke with a person named Walter, who told me that no one had come out before because I hadn't left a credit card number. I told him no one had asked me for a credit card number during the previous call. After giving my credit card information & discussing possible new charges, I was told a technician would be out the next day. Again, no one showed up or bothered to call me to reschedule. The following day I took my vehicle to an auto repair shop to have the battery checked & was told the positive battery terminal was loose. The auto body repairman also asked me who had installed the new battery because he claimed whoever did it had secured it improperly. I was also missing not one, but two push rivets from the battery containment area. The loose battery terminal was tightened properly, as was everything else surrounding the new battery. He also offered to replace the missing push rivets, but unfortunately, didn't have the right size for my make of vehicle & suggested I try to find some at an auto parts store. I haven't been able to find the correct-size rivets yet, so I'll have to make a special trip to a dealership to try to find some. I finally heard back from 1-800-Battery by text a day after taking my vehicle to the auto body shop. The text said a technician was on his way. I immediately called 1-800-Battery & spoke with a person named Travis. I canceled this service & I also expressed to him how frustrated & disappointed I was with the service I had received. Travis said he was sorry, but never offered to make things right. The least he could have done was to offer to replace the missing rivets, which weren't missing before the new battery was put in. I will not use your company again & do not recommend it to anyone else.
