information given differs all the time

I called in on the 23rd, spoke to Ayanda I requested a settlement amount for my laptop and cellphone he was able to give me the details and the next day I got an sms with regards to my laptop. Saturday a debit order went thru my account. I called in again spoke to Gladys (not sure of the name ) she advised me not to pay the amount I was told by Ayanda as new calculations will need to be done. Which I understood. She said she will send an email to he retention department and they will do the calculations. Icalled again on Monday to find out if they had sent my details. Spoke to chantel with ref ***. She said I will get feedback within the end of the day. I called in again on Tuesday spoke to Zipho who said he will email chantel to find out what's happening. He gave me chantels details and the number he gave me went straight to switchboard so that was an obvious downfall, as I had to speak with another agent. I am glad Simthembile didn't promise me anything, he did mention that it takes a while. He apologized on behalf of the other agents, he said he will try help me out. Gave me ref ***. I want to cancel the contract, pay all outstanding fees due.
