Best service ever

I dont know what is going on with Cell C but i have had nonstop nonsense with them for the past year,

First they debit me twice, then they charge me for a failed debit order but i changed it from Debit order to Cash in December because they were constantly double debiting me.

Now for the past 2 months they debiting me again and when i phone in i get told firstly they cant verify my details and then that debit order was never changed, i am extremely upset with Cell c and cant wait for my contract to come to a end so that i can rather just go onto prepaid,
