Problems arose from our order in June 2017 where our order was forgotten then shipped from the USA to Sweden until their rebuke of the original invoice and conversion of US dollars to GBP. Attached are email strands and original invoice (which was paid in full). In these you will be able to see that the service and information we have recieved has been confusing to say the least. The invoice was sent to us in US Dollars with US Dollars being the specifically requested currency. We understood this as the delivery was sent from the US. Fast forward to today where we get another invoice with another outstanding amout with another amount stated in the email. As you may be able to understand, our faith in McGraw Hill is below 0. Each phone call and email claims that we are at fault and should have known, we have misunderstood or should have even adjusted the invoice to GDP!!! What sort of way to treat customers and run a business is this??? We are not in the business of trying to edit and change invoices nor do we infer to our customer that they are the ones at fault! My anger and disappointment goes past anything I have ever experienced professionally. See attachment for some of the email correspondance. -21st November 2017 we recieved a reminder that we owed 2825.80 Euros -4th January, 2018: email stating, 2826.80 USD -16th January, 2018: 2826.65 USD -Invoice of 3171.65 USD was paid in full by us (see attached invoice) - Emails sent by us, voicing our confusion of all the different currencies used and different amounts. Reassurance was given by McGraw Hill that we had paid in full and that we had a credit of 345 GBP. -March 2018: We receive email stating that we paid in the wrong currency despite the invoice and reassurance that we had done everything correctly. We were also told that we should have adjusted the invoice, that we should have known and now we are to pay the mistake that they had made. All the while we have received statements of account where it calculates that we have a credit. This is far from our problem or mistake. It is not our responsibility to assure the quality or communication between the US and International divisions. In any other company, this would have been resolved without us being blamed for the mistake or having it inferred that we should have know or that an invoice was actually irrelevant. It would seem that McGraw Hill is unable to take full responsibility for their mistakes and would want to keep customers. This is a very big shame as the Everyday Mathematics materials are fantastic and McGraw Hill does not do them justice. We will not be having any further dealings with McGraw Hill and will be sending a formal complaint higher up and to the developers of this program noting that this lack of accountability has lead to the loss of a willing, long term customer. Might I add that the service we have received at every point has been sub standard and our requests to go further are not heard. You get studk with the customer service person you have even if they cannot do anything to help.
