How have you concluded that the £14.64 is a landline increase ? , presumably you have broadband , if you only have a phone landline and no broadband, and don’t make calls it’s a bit pointless having a line at all .
Broadband has been for decades , a single fee , it isn’t subdivided into broadband and line rental , it’s just one amount, a typical £30 monthly broadband bill is just £30 , not £20 line rental and £10 broadband making £30 in total , it’s just broadband £30, so is it the case your broadband bill has gone up by £14.64 ?, how can you attribute the increase to ‘landline’ when there isn’t an item on the bill for ‘landline’ ?
Obviously if you were paying somewhere between £10-17 for 700 mins and have changed to PAYG that’s around £2-5 then your bill will reduce by the difference in price ( providing you don’t actually make any calls , or very few calls ) , but there is the March 31st increase to take into account .
It’s pretty likely your last bill showing the increase is in part for days after the 31March increase , depending on what other services you take and what you were paying for them , it’s likely the reduction in price by taking PAYG instead of 700 mins , isn’t as much as the average 8% increase on the remainder of the bill, so overall the bill increases.
Post actual facts and figures to be sure, but bills after changes are made are notoriously hard to follow with part month credits and debits
