My Account with Teljoy is one Big Nightmare

Samsung 40L Stainless Steel Microwave ( ********** 4) Today I received a bill and they will debit R905.44 on the 1st October 2018. That will be the same amount they debited last month, but July 2018, I were informed by Nonhlanhla Mazibuko and Kavitha Le Roux that end of September 2018 I will only pay Pro Rata of R99.94 on the appliance. I send an email to Nonhlanhla Mazibuko to clarify why will Teljoy debit the full installation and not the pro rata rate, she rep**** by saying that on the 1st October 2018 will be my 3rd instalment, shocking.
