According to the rules of supply and demand, the seller will lower the price of telephones.
Supply and demand is the relationship between how many items providers want to sell at a given price and how many items consumers are willing to buy.
If buyers are not willing to pay the price the seller charges for the telephones, the demand decreases, because interest in the product decreases. If the demand is lower, the way to rebalance the provider-purchaser relationship is for the provider to lower the prices.
