I purchased 4 packs of hair extensions and a professional membership from perfect locks on June 4th, 2018 in the amount of $437.61. After installing 3 of the 4 packs of hair extensions on my client on June 15th, 2018, she returned just over a week later to have them removed due to the hair discoloring from blonde to orange. My client has been getting hair extensions from me for years, and we have never had this problem before with other hair extension brands. I contacted Perfect Locks on June 27th, 2018 via phone and e-mail to explain the problem, and they requested I return the 4 packs of hair extensions so they could examine them to see what went wrong. I returned the extensions to Perfect Locks on 7/2/2018 using the shipping label they provided me. In the meantime, I had to purchase new hair extensions from my previous local supplier, and install new hair extensions on my client which cost me $325 for the new hair extensions and $200 for my labor, all of which I had to comp the client. A representative with Perfect Locks contacted me via phone on July 12th, 2018 and told me that upon their examination of the hair I had returned to them, they had concurred that they had sent me an old batch of hair and would resend me 3 new packs of hair and only refund me for the 1 unused and unopened pack of hair. I told them that I would not accept their offer since I had already lost $525 for my labor and the purchase of new hair extensions to fix the problem they had caused. I explained that I expected a full refund for the defective hair extensions that I had returned to them and the membership fee. The representative then told me she would discuss the issue with her manager and get back to me. I have not heard back from them and I am now in the process of trying to complete a charge-back with my bank.
