DStv adding to my account for switching but market it as free service.

DStv advertise a free service which they bill. I had a duplicate installation at home and holiday home. DStv advertise that clients can switch between home and holiday home free of charge. NOT TRUE. Over many months I was billed additional amounts when switching, irrespective if I switch via their website, via the call center, via Whatsapp or any other way. It always took a lengthy call, lots of explanation, operators that cannot fix the problem, promises that they will escalate, correct and come back to me... NEVER EVER CAME BACK... In November they added an amount after switching to my account over month-end. Then they decided to disconnect me and charge a re-connection fee ... took it from my December subscription. Now in January, they insisted on my paying the re-connection fee. I refuse to pay more on grounds of them not competent to deliver what they market. I locked my subscription. I insist on getting the pro-rata money back for January 2020. One smart call room consultant once said that the additional fees are automatically billed if they do the switching in the wrong sequence. I advised the other operators accordingly when necessary. Their instance in me paying more for their mistake cost them one more unhappy subscriber. One would not **** the business, but believe me, the trend is busy ****ing DStv.
