Thank you for your reply Dave.
Unfortunately despite our exchange of emails, you don't appear to have read what I have said over the past few days.
the 1 that is due to be paid, is now being paid their 2nd cashback payment. The complaint was referring to their 1st cashback payment, which they submitted in October and should have been paid by early December. You did pay this, but you paid it later than your terms and conditions allow.
The one due to Orange changing some billing information is yet to be resolved by you, and does not appear to be due to the customer breaking any terms and conditions.
There was a fourth complaint relating to cashback.
There were also other complaints relating to elements of your customer service. In my above post, I said that most complaints relate to cashback. But complaints also related to waiting 45 minutes trying to call you to return a faulty phone before giving up. I advised that customer not to try again, and to just return the phone directly to Nokia for repair.
We have received no complaints about other retailers in the relevant period (since October) despite generating significant numbers of leads.
As for what is too much to handle, please bear in mind that I
am a full time student. So this must time spent on dealing with complaints about one and only one retailer, is in my opinion "too much to handle".
