Cheunkz, Jul 5, 2019 : I had recently experienced the worst customer service I have ever encountered. I was participating in the trade in program. Which I requested a trade in package for the promotion ($250). It took the 3rd party 5 days to send the kit out. I had sent in my phone for the voucher option due to the promotion ending June 30th. Which requires 15 days before you can claim the cashback. I took this option, while my phone plan was still activate, losing about a month of usage. After I had sent out my device. I had then received a value of $0 due to activation lock. The phone was factory reset, unattached to google, and purchased from Oneplus(I had logged on and confirmed everything worked, then factory reset again). I had been told it was due to an activation lock issue. I then contacted Oneplus customer service. I was talking to a service rep. I was trying to determine what the lock they claimed was on the device as I would be in exactly the same situation if I had received the phone back without a clue of what the lock was. After being told they could no get any information as they do not have direct contact with their 3rd party trade in partner(Phobio). I had requested a manger/supervisor. They ensured my that they would find out more details and contact me within 24 hours. I had not heard from them so I had called back. Same scenario with no additional information, promised to call back in 24 hours/send and email update. I did not get contacted. I called in again the next day and was told that there was no way for me to be transferred to a manager/supervisor. So who did I speak to last call? They said a management staff will contact me within an hour. Nothing. I called back again the next day. I had adamantly requested to speak to a supervisor/manager, was told they don't do it that way. After a while of back and forth the rep had talked to the Manager/Supervisor however they were too busy to answer and would call me back. Again nothing. I'm astonished how much lying there is within this company and how much information they do not have with their trade in partners. Unfortunately, this has not been solved I think due to the trade in promotion being reduced back down to the normal amount($120). This was probably the plan to ensure that I would not be able to get the $250 trade in value. Is this how a company operates? lying to their customers and giving them the hardest time possible to get any information. A week after I had enough. I just want anyone else thinking about using the trade in program, or any other promotions/issues they have to expect this treatment as they don't seem to care about their customers at all. Thank you for reading if you got this far.
