Ismart Telecommunications : NO Business Ethics, Stupid and inconsiderate

This is really annoying as I have been reporting one over and over again I call this bull****. Since March 2020 I do not have access to my contract it says the sim is not registered. The three operators said they will get back to me till today nothing is happening but Ismart is still deducting on my account on a monthly basis. Ismart please terminate our contract and return all my money from march 2020 please because this is useless. This is bull **** because they quick to take my money but fail to deliver. Even the phone given to me ****en useless and not up the current technology standards. I am not renewing contract with you as you have shown me that you do not business ethics
