I have the direct debit tariff setup for the pay monthly sony xperia m4 aqua black phone. But I'm not being charged by direct debit for the handset. The handset should be £7 a month. The tariff direct debit is £5 a month. I have phoned customer services several time for the handset direct debit and they have my bank details. Can you please sort this out for me. Or if not can I pay by automated phone service for the handset or by online for the handset?
