Phonetradr still has room to improve

I bought a Samsung zflip with phonetradr that process was great. But a few days after I got the phone I realized it had an issue recording voice notes on whatsapp. I sent a query about this, the phone was collected to be fixed by one of the technicians. It came back and after a few days had the same issue again. This time my whatsapp messages and calls were ignored and I have not received assistance. Phonetrafr needs to improve in this regard otherwise I would have given them 5 stars, I can't even give them 4 because this issue was never resolved and I was ignored on various occasions of trying to query the phone issue a second time.
