I bought a nokia for the first time last month (G22) and found that the call sound was tinny and my microphone was crackly. When trying to organise the return procedure the customer service team both online and over the phone were extremely rude and unhelpful. I repeatedly tried to organise a return with them and the courier would never turn up to collect the phone for return. I asked the nokia customer service team (both online and over the phone) what would happen if the courier still didn't turn up outside the 30 day refund window, and I was told I wouldn't be able to get a refund, even though the error was with the courier they were using.
