LAMB switched me absolutely seamlessly in my first year but the second year has been the total opposite. My existing supplier is objecting to the switch. I have delegated to LAMB to solve this issue for me (seeing as they are the switchers). This problem first arose in December and it is still not resolved. Every time I call LAMB, I have to run through the whole story every time. Many of their solutions thus far have been repeating the previous task expecting a different result. Without LAMB, I could be with a new supplier by now. Instead, I am stuck with my old one paying a more expensive tariff. All in all, seriously frustrating. Once this is all done, I will not be using LAMB again.
