Bunch of sharks that take your money, send the wrong part and refuse to refund. Be warned!

On 9th February 2018 I ordered a boost sensor for a Nissan Xtrail. After sending them a photo and providing the Model and year, Desigan Reddy promised me the part they had had the identical part number and it would be shipped and i would get it in Cape Town on Monday on Monday 12th. Well it eventually arrived on Wednesday 14th. And it was the wrong part. It definitely did not have the same part number and was not even the same size. There started my so far futile attempts to get a refund. Their courier picked it up from me on Friday 16th (after promising me they would collect it on Thursday 15th). Then I was asked to Contact Desigan's Manager ,Timothy, who told me on Tuesday 20th they were still waiting for it from their courier but that my refund details had been submitted. I sent messages on 1st and 3rd of March to Timothy's WhatsApp number that I had used all along, only to be told "Which refund this is nash and not Tim". Further messages to this WhatsApp number have been ignored. I then managed to get Desigan on their landline on Wednesday 7th March, where he checked up and told me they did not have enough funds to refund me but that it had been sorted out and I would receive my refund today. I still do not have the refund and am unable to be put through to any manager accounting person. You should seriously think twice about doing business with this company. They do not play nicely.
