You can't until your contract is near expiry then give 30 days notice, unless you want to pay a large exit fee before that.
I passed on a retentions deal and in my notice period after being with VM since 2007 (bar one year when RiverDelta CMTS was useless and then got replaced by Cisco (now Arris), so I came back). Offshore Retentions represetative still wanted an 18 month contract (a sticking point) - despite no new kit costing them - and I don't like agreeing a legal contract to an undocumented price increase amount with no escape clause. That would have been 2 price increases - and the retentions offer was still more expensive than local ALTNET that does symmetric 1gbps for £29.99 and BT FTTP where 500mbps can be had on deals around £30.
VM wanted £75.07 for 500mbps Broadband ONLY. Admittedly my VOLT upped it to 1gbps BUT VM always said VOLT was free and a benefit of being with O2. I've put up with O2 (rubbish data speeds due to overloaded cells) but that will also be getting the boot now on principle.
VM failed to notify my contract options and new standard pricing by letter or email yet again, and failed to inform me of my price increase amount by email or letter. Only when I went into the app did it indicate. I actually missed being exactly 30 days before end of contract pricing came into force.
The rest of the family is sure to change from VM as they have even more choices than me where they live and they look to me for advice as technical job role 😉 Similar, at my partner's house, at end of contract not far away, VM will get the boot there as well. So not a good day for retentions off-shore - they didn't retain a thing.
So they lost Stream Subscription revenue + O2 revenue additionally on my account alone. I don't think retentions will ring back, the offshore team were quite abrupt in their handling and first woman wasted my time and then randomly passed the call to someone else without saying why even causing me to have to repeat all the security question answers again and my best contact details.
