Appalling Service by MiWay

I write this with a heavy heart, as I genuinely believed that the company was being helpful initially. However, 3,5 months after logging my claim for a faulty heatpump, the problem has still not been resolved. I have been more than accommodating, allowing a variety of service providers into my home multiple times to repair, removing the unit multiple times to "bench test" only for it to run for 10 minutes and cut out again. I have to constantly follow up to find out what is happening, spending hours on the phone. About two weeks ago MiWay had finally conceded the heatpump was not repairable and apparently authorised a replacement unit. Between MiWay and there service provider ITU Assist, I have made close to 20 calls during the past 2 weeks trying to get confirmation as to when they will be coming to replace the unit. Everytime I just get platitudes from the agent speaking with me, saying they had the service provider on the line and they will be making contact to arrange a convenient time. My patience has now dried up! I have spoken to Tracey Tshuma (Team Manager) who has escalated my issue, and has also promised to escalate to a lady called Amanda Botha. And I am still patiently waiting for feedback! This is a disgrace! They have no concept of customer service. Shame on you!
