Network faults

Smarty have been fixing a fault in L3 5SA LIVERPOOL for the past 11 months, signal is terrible with either no service and dropped calls, in this area it’s not possible to use the Vodafone network yet according to smarty and internet wise the 4G drops too. 
Does smarty always take this long to fix Network faults ? They obviously know about it as it pops up on smarty’s network checker.
