o systematic random sampling
o voluntary sampling

Explanation:

Voluntary sampling occurs when individuals decide on their own whether to participate in a survey. Here, customers are asked if they could stay on the line to answer survey questions, meaning it's up to their own - will. Systematic random sampling involves selecting elements at regular intervals from an ordered list. Cluster sampling divides the population into clusters and then selects some of these clusters. Convenience sampling selects individuals who are easily accessible. Since it depends on customers' voluntary participation, it is voluntary sampling.

Answer:

voluntary sampling
