****med by free upgrade on my rewards

Last year December dstv had a competition for rewards members whereby you open a cracker on the dstv app anf you could win. I won free upgrade to DSTV Premium and thats where my nightmare began. I was upgraded during the same month of December and the upgrade was only for a month (30 days) Unfortunately because i had just switch my payment method to debit order I thought the debit order will go through early like other service providers but unfortunately it did not and my services were disconnected, fair enough we all know if you don't pay the services will be disconnected. Come month end of January boom 2 debit orders went through my account 1 was R940 and the other one was +- R250 wich in total was around R1200. Wnen i calked multichoice i was told it was because i was on premium hau i never requested an upgrade and i asked the agent to downgrade my services back to compact and she promised she would and that the difference will be refunded back to my bank account after 3 days. Three days passed and 5 days later i called multichoice again and the lady that was assisting me on the day told me that they were trained to tell us that refunds will take 3 days but however they take much longer than that and advised that i should go to my bank and reverse the money because i wont get it. I did just that and my services were disconnected again which i still understood. When i checked for amount to pay on the app it showed just over R1200 again. Fast forward to today i phoned in to enquire again and was told that i should pay R519 as that is what i owe multichoice and i decided to pay R570 and i called the call center again and i was told that i still needed to pay R680 for my services to be reconnected which when you add the 2 together will still equates to R1200. Im sitting here watching channel 100 again. Is multichoice ******** us??? They talk about free upgrades but you end up having to pay for it. I am very upset and annoyed
