Unfortunately I have to call them from my three phone, which is an old LG.
So, Today I spoke to Mukhta, who eventually put me through to Parshuram in the customer options team, who eventually began mumbling the same old mumbo jumbo, "what is on the system is correct sir...", who I eventually had shout at to get him to listen to me.
Parshuram then told me that my case was being dealt with by Chanprashekhar Saroj, and that he would give me a call in 3-4 working days.
Its just delay tactics, but I will wait the 3-4 working days and nothing more before canceling my direct debit.
