Follow up with the last Netstar complaint

So last week I complained about Netstar on this platform and they responded by saying they will call me to resolve my issue, no one called a few days after they came back to this platform to say my issue has been resolved and today I received the following message: Dear Netstar Client.Your debit order has returned from the bank.Please urgently pay R135.00 at Absa Acc: *** Ref ***1.Or call us on ***.....I know when I get paid they will definitely deduct, how many times must I deal with this, i only have a tracking device with Netstar but through my insurance, they never used to deduct until November, I have been trying to tell them the whole time, but I am still dealing with this issue, NETSTAR PLEASE REMOVE THIS DEBIT ORDER FROM MY PROFILE, I DO NOT KNOWB WHAT IT IS FOR ABD I NEVER SIGNED UP FOR IT
