Makro on line

I ordered a solar pool pump for Makro on line on the 1st of September 2019. Delivery was made on the 19th. The order was missing parts. I have been trying since then to have my parts delivered. I have made phone calls and sent at least five e-mail. Every time I get a reply that somebody will get back to me within 5 working days. One time I phoned I was told I had to send photo's of the missing part . I could do this only because I could see it on the box but the other part was only in the advert. This was sent on the 4th of October. I sent another message on the 9th of October. I am yet to get feedback. I have a solar panel, that I hope works with the pump as I am unable to test it. So should I eventually get the part, I might be told I waited to long before testing it and tough luck you bought a dud. This was a pump bought from another company. Makro acting as an agent. My stove I bought through Makro themselves was not a problem, which is why I decided to purchase this pump from them. Obviously a big mistake.
