De Longhi pathetic service

Our portable air conditioner was not doing any cooling, so I booked it in at the De Longhi support centre in Constantia Park, Roodepoort on the 7th February. I then called them on Friday 9th Feb to see if they had a quotation, and they said it would be sent to me, but nothing was received. The following Tuesday 11th Feb I called again, and was told again that the quote would be sent. Still nothing by Thurs 13th Feb so I went in and met with a person, who assured me that I would receive the quote the next day, 14th, but nothing again! I called again on Mon 17th and was advised that the unit needed to be re-gassed, and was then given a long story about a change in suppliers and that that the estimate was R1500! I then received an sms on 18th Feb with a quotation for R2315! This is pathetic given that they took two weeks to get to this point. I then collected the unit as I was utterly frustrated at this lack of service. Needless to say I will not be purchasing items from De Longhi based upon this experience.
