Terrible customer service

I did an upgrade from LTE to Fibre online with Mweb. Firstly it took forever to get sorted out not because of the covid lock-down but because the technicians they sent from Metrofibre could not get the fibre installation done the first time. I wish i had kept a proper record on this installation which took place over the past 5 months. Eventually I was successfully connected on the fibre network on the 16th may 2020. Now comes the next load of bull****, i get charged for both the Fibre and the LTE services because of some nonsense about not requesting the correct upgrade or using the incorrect upgrade request method or product. I'm a home user not a business or corporate. After sitting on the phone with 3 different people for 31 minutes i get told that there is not much they can do about it as it's my fault for ordering the incorrect product online. They can do a instant cancellation of the old product but i must still pay for last month and a portion of this month. What a load of horse ****. There is no way of getting through to any manager or person with some authority you just have to accept what you are told and have zero recourse.
