If a customer has an outstanding amount on their account, reminder letters would be issued periodically to the billing address, and/or contact would be made by telephone/mobile/sms.
It would certainly be very unusual (something I have not encountered myself) for there to have been no attempts made to contact the customer over such an extended period. I would need further details before I could explain to you why this happened.
Customers don't need permission to switch suppliers; they can do so without notifying their existing supplier directly. I am sorry if you were informed otherwise. If a returning customer still has an amount outstanding, however, they would either need to clear it, or make an arrangement to clear it, before we could re-register them.
I also received a similar call this morning to advise me there was an outstanding unpaid ESB bill to the amount of €120.
On further investigation it appears the direct debit for the above amount was not withdrawn. Great, I have an additional bill to pay!
I intend to pay this bill but it will not be a once off payment of €120, I intend to pay it back over a period of time.
It is quite strange how such a large company can let something like this happen but very unfair to spring it on customers over 1 year later.....good morning, you have an unpaid bill of 120 euro!!! The direct debit was setup to pay the ESB ontime, why didn't you take it at the time of the final billing!!!
I'm sorry that this has also been your experience. I can understand if you feel frustrated by this.
If you would PM me your account details I will have the matter investigated for you. It may also help us to discover if this has been the case for other customers; we could then take appropriate action before we spring anything on them, as you put it.
Again, my apologies, but I look forward to hearing from you,
