Pathetic after sale service - faulty unit

On 29 December 2018 I bought a Snowmaster 15kg and a Zingo X100 from Dion wired. When we got home the icemaker did not work, we had to go back to the shop and have it replaced. So on the 18th of January it was my son's birthday for whom we bought the zingo. He used it once and then it broke. We dont know what is wrong with it, I think it isn't charging. I take the zingo to Dion wired in Mall of Africa and is met with such rudeness words cant even discribe it. I ask for the manager and out comes Cindy, she is the sales manager. I explain everything to her and ask for a loan unit even if it is second hand. My child is so unhappy about this gift that is not working. She doesnt even try to meet me in the middle and immediatley just says no. I ask for the store manager and get told he is out of the office. I then phone the head office and they tell me they will get the general manager to contact me. I get a call from a very helpfull Martie and I again explain the situation to her. All i wanted was a loan unit until i get my son's zingo back or get a new one which according to them can take up to 21 days for the report. In the meantime Cindy got hold of Kas (store manager) and she talks to him, he says to her tell the customer NO, we wont give her a loan unit. I then say to Cindy I want to speak to Kas myself, she phones him back and he refuses to take my call of speak to me. Martie then phones back and says the general manager of the region Heinrich Willers is not in the office the whole day but she phoned the supplier and they dont have loan units. Now my point is, i didnt buy the zingo from there supplier, I bought it from Dion wired. I a furious and they dont care. Both items that was bought from them where faulty and had to be returned. The attitude and customer service sucks and I will never ever buy anything from them again. I will also tell anyone willing to listen to NEVER buy from them. They are quick to take your CASH i might add but the after service is a disgrace. I want a loan/demo unit from then until I receive mine back. Is that to much to ask. I expect Mr Heinrich Willers to solve this problem as clearly his staff are imcompetent. This is unaccaptable and I will take it further than just hellopeter.
