£35 activation fee is a bit excessive for an existing customer.

I was considering transferring my SIM to o2 Via a Volt Package that would also upgrade my BBI from 500mb to 1gb with a new 24 month contract, and having both services on the same bill however an 'activation fee' of £35 is unreasonable and a deal breaker.

considering I'm an existing customer and its a basically a clerical update to my account, with me doing any manual installation locally with existing infrastructure/equipment, I understand equipment needs to be sent to support the 1gb speed, this should be at max a £10 shipping fee max, not £35? how is this justified. 

£35 negates any saving I would have made when changing mobile provider over a 2 year period and is a deal breaker unfortunately :(

I get access to corporate discounts, yet anything to do with VirginMedia requires 'New Customers Only' I can't help but feel like a second class customer at times.

Unless this fee is waived/credited as part of any upgrade, I will need to seriously consider another provider when my contract is served, as my requirements are changing and I don't feel like I a valued customer being charged £35 to update my account.
