Bad service

I am so discussed with the service defy is giving on my repair. My unit has been giving ongoing problems. It was arranged with Basil to collect my unit 3rd of May 2023 with time i message him to ask if they still coming no answer obviously. I left multiple messages for him and Christopher the regional manager from the 3rd they didn't bother contacting me. Instead they shift between the two branches Bellville and Montague gardens. No apology from Basil not collecting the unit. Yesterday it was arranged for today collection 16:15pm seen that i had a meeting to attend at 17:30pm and had to leave 17:00pm, 16:45 i phoned to ask if anyone planning on coming it was said they are only leaving the premises. Robin phoned me to reschedule for the 10th May 2023 the morning i had lost my cool. This has been going on for so long and i have to stay calm for all this time. Its not fair to keep arranging and Defy don't stick to the arrangements and pretend it was never arranged before. I have send x2 complaints in to no reply either. I wish i never bought this unit at Defy is just interested making money and don't care about the clients. .Ref *** 18th April 2023. my food got spoiled and my children are suffering but why would defy care. They don't even deserve one star.
