Pathetic Service

On 14 May I purchased a spare part for my Hisense Gas Stove, the cost of the part plus the delivery charges came to R448.08 which was paid to Hisense on the same day. The part was delivered to me on 24 May, but unfortunately was an incorrect part. On 25 May I emailed Hisense (Jurgen) notifying them that the part delivered was incorrect. I received a reply from Jurgen on 2 June advising me that I had ordered the wrong part and therefore I would have to carry the cost of returning the incorrect part to get a replacement. On 3 June I emailed photographs to Jurgen showing that it was impossible for the part supp**** to fit my stove. No reply. On 14 June I sent an email to the Service Manager requesting assistance. On 19 June I received an email from Lushay requesting a copy of the invoice. This was sent to Lushay the following day, 20 June. Since then I have heard nothing from Hisense. In the meantime I cannot use that burner on my stove and I am sitting with a part which cost R448.08 which is of absolutely no use to me.
