Walka not working due to DPP plan

so in the past few months I have had endless problems with this company starting off with the Explora deal. I have been a client with multichoice for many years AND NEVER HAD PROBLEMS TILL THIS EXPLORA ****, I have a Walka 7 that worked perfectly until Saturday, I called multichoice only to be told that since I am on the new payment plan for the explora I will need to pay a separate subscription for the walker as it only works if you are on the normal premium package. I HAVE PAID FOR A WALKA AND AN EXPLORA NOW YOU WANT ME TO PAY ADDITIONAL SUBSCRIPTIONS YOU PEOPLE ARE *******S, YOU ARE *** AND YOU HAVE NOW LOCKED ME IN A 24 MONTH CONTRACT LEAVING MY WALKA USELESS. YOU WILL PAY ME BACK FOR MY WALKA AND I WILL BE ESCALATING THIS FURTHER, DAY LIGHT ***, NO RESPONSE FROM THEM CLOSE TO A MONTH THEY DONT CARE
