Payment Issue

On Saturday, I called to notify Foneyam about a payment issue I was having and I was assisted by a very helpful employee who told me he would "extend my contract" so that I only have to pay in December and can skip this month. Our call was cut short before he could do it and he told me to call again and another agent would do it. I had to call twice before getting assistance and the agent who assisted me told me she could only change the payment date not extend my contract. Yesterday I got a call from another agent stating that I did not pay in October and my contract will be terminated. This is very confusing as I paid in October and I have the sms showing that I paid. It's only November that I haven't yet paid. Please assist. My ID number is: ***. My phone number is ***. My reference number is: ***.
