Answer :
Final answer:
The reasons that cannot be used to extend appliance repair deadlines include personal convenience, lack of funds, and lack of knowledge about the repair process.
Explanation:
One reason that cannot be used to extend appliance repair deadlines is personal convenience. The deadlines for appliance repair should be based on the urgency of the repair needed and the availability of the repair technician. Another reason that cannot be used as an excuse to extend the deadlines is lack of funds. If a customer cannot afford the repair at the moment, they should seek alternative solutions instead of delaying the repair. Lastly, a customer's lack of knowledge about the repair process should not be a reason to extend the deadlines since it is their responsibility to communicate their needs and concerns to the repair technician.
