Disgusting Customer service

I received a call from Mondo on 9 May 2019, they have offered me a cellphone contract, was told my phone will be delivered 3-5 working days. I have done multiple follow ups with them, they kept telling me they can't find my order, my husband called into their offices and they told him last week Thursday stating that they were having system issues and whatever order placed on the 9 May 2019 was only loaded on 16/05/2019, however, when I did my follow ups, they kept stating that there is no order placed with their company, I have stated that I have a recording of this. Even via email, they were unhelpful. My husband called Vodacom directly and they could see that it says in progress, but because they didn't do the order with me, they couldn't give any information. Mondo has advised that someone will get in contact with me as this is the 2nd time this has been escalated to them and no one has called or even emailed me. I'm highly appalled by the service. They are very unhelpful.
