Tips for calling customer support include being polite, avoiding unnecessary details and escalating the issue when necessary. If possible, the customer should call during nonpeak hours, so the representative is less likely to be stressed or rushed.
Being polite is useful because representatives are more receptive to customers who treat them with respect. The customer should avoid excessive details because the representative's job is to handle the issue as quickly as possible. Unnecessary details slow down that process.
If the representative can't provide an acceptable resolution, the customer should escalate the issue by requesting a supervisor. Supervisors typically have more options for resolving the situation.
