Home-Connect poor service

I app**** for fibre installation with home-connect beginning of October 2021,I was advised on cancelling an ISP which was showing then,to my surprise the active isp then was from Rain,Rain made me pay R116 as a cancellation fee for a SIM card bought 2019 and was never activated,we have a recorded phone conversation from their agent confirming that she sees the Sim was never activated,well I paid then the R116 cancellation fee as I really needed to get wi-fi installed for my sons studies,cancellation was successful and I forwarded home-connect proof of cancellation fees,only then they came to do the installation for me but after I emailed rain quering the cancellation fee they wanted from me for a Sim that was never activated but I got no response,instead they told me they’ll deduct a R250 am owing as it is standard for them if you used their Sim,refused to pay another R250 on the Sim which was never activated,So now just yesterday Home-connect calls me only once and happened to miss their call,without checking with their Accounts if I paid for my Wi-fi of which I did on time the 22/11/21 or making sure they get hold of me inform me if there’s any problems No what they do is disconnect my internet, I emailed them yesterday and this morning demanding an explanation No my emails go unanswered, still sitting without Internet,no phone call, returning of my emails non whatsoever, Sad part is I paid and even sent them proof of payment but they quiet.
