Synchrony Financial Credit Card Complaint

Synchrony Financial Credit card department,

Payoff process Pennsylvania

While I 'm waiting for - to be re-opened, another issue has arisen. I asked Synchrony Bank to allocate payments to - charges on my account that expired in -/-/-. They complied with my request, however, then they sent me 35 emails and a letter via postal service to confirm they had allocated the payments. Is it their standard company procedure to notify a customer that their request has been completed by sending 35 emails and a letter?
