Worst Insurance and in-store customer experience

I am extremely disappointed with MTN and their Insurance company. My phone (Huawei P20 lite) got ****** on the 5th of December. A claim was made the next day at MTN to get a new phone. I only received that phone on the 14th of January, after continuously calling the insurance company and spending my time and money driving to MTNs to help assist with the time and dates of the arrival. I was never properly helped or told a correct date. Only kept on held or said they will call me back. Then after receiving the phone on and only opening it to install apps I realised that phone could not connect to our 5GHZ fibre wifi network and it was also in the wrong colour. So I sent it back hoping to receive to phone I am PAYING FOR. But no. It is currently the 14th of February and still no phone or assistance on the date of arrival. This has honestly been the worst customer experience I have ever got and to top it all of, they are sending me back the phone they gave me on the 14th. So no I am two months without a phone, paying for the full contract, getting no help form anyone after calling probably 200 times. I can't wait to cancel this contract and be rid of MTN. If a manager or someone from the company could call or email me and assist me with this wrong doing, I might consider staying. ***
