Lack of follow through from Trojan SA

Since 16/4/21 I've been trying to get a picture of a part for my exercise bicycle that I have ordered from Trojan SA. The service agent told me that they would send a pic of the part together with the quote, which to date has not happened. I received the quotation on 20/4/21, and have made umpteen calls to both Trojan as well as their Service Division, Evolution Services. Managers are never available, and the Supervisor at Trojan that I spoke to on Friday 30/4/21 assured me that he would personally see that I received the pic by close of business that day....Well, it STILL has not arrived. The thought process behind the offer to send the pic, was that i did not pay and receive the incorrect spare part. It was offered to me by the initial agent I spoke to on 16/4/21, and not something that I requested out of the blue. At the time I thought it was very good business practice on their part. Needless to say, the quote was only valid for 7 days, and I was notified that it had expired. There was an option to respond, to which I did, but no follow-up has come from their side, as I am based in Durban, and there are no agents here. I am now sitting with a machine which I cannot use......
