Eir has claimed improvements in its customer care and issue resolution times for its fixed line service, following the publication of the latest data from the telecoms regulator.
The company, which has faced significant criticism in recent years over its customer service, said the ComReg research shows that in the first quarter of the year the number of complaints it received for its land line and broadband services fell to 22.3 per 100,000 from 30.1 the previous quarter.
That compares to 24.7 per 100,000 for Sky and 36.4 per 100,000 for Vodafone. Virgin Media had a better record than all the others at 13.7 complaints per 100,000.
However, when it comes to mobile services, eir's record is still less favourable than its competitors.
Between January and the end of March, it had 2.4 complaints per 100,000 customers, down from 3.2 in the previous quarter, but still higher than mobile provider Three at 1.7 and Vodafone at 2.1.
In recent years, eir has brought its customer service back in-house after many years of having it contracted out to third party providers.
However, the arrival of the pandemic complicated the process significantly, as many customer service agents were forced to work from home.
Nonetheless, eir claims it is delivering strong and consistent improvements in the area with the volume of complaints against it dropping consistently over the last six quarters to their lowest point in seven years, when compilation of the data first began.
"Since the third quarter of 2020 complaints from mobile customers have fallen by 91%, while complaints from fixed-line customers have fallen by 89%," said eir CEO Oliver Loomes.
"This represents a remarkable turnaround from 2020 and demonstrates our utter focus on improving the quality of our customer service.
"We continue to expand our customer care operations. Most recently we opened a new Waterford care hub, with an additional 40 jobs there, and we continue to recruit across our care hubs in Sligo, Cork and Limerick."
Overall, the ComReg Consumer Line Statistics Report shows that there were 12,400 contacts and 4,600 issues reported to it in the first three months of 2022, broadly similar to the previous quarter.
295 of the issues related to mobile services were in connection with eir, up 51 on the previous period, while 278 were about Three and 286 were recorded for Vodafone.
On the fixed line front, there were 756 issues reported for Eir, down 196 on the fourth quarter of last year.
There were also 376 for Sky, 220 for Virgin Media and 421 for Vodafone.
Loss of service, billing after contract cancellation and billing more than the agreed amount were among the top issues raised by eir customers in the period.
