Hello my name is ***** ***** I will help you.
Do their terms and conditions say you must give 7 days please?
When did you join?
Ok. Then you could argue that the 7 days terms are unfair as per the Consumer Rights Act 2015.
This says at S.62:
62Requirement for contract terms and notices to be fair
(1)An unfair term of a consumer contract is not binding on the consumer.
(2)An unfair consumer notice is not binding on the consumer.
(3)This does not prevent the consumer from relying on the term or notice if the consumer chooses to do so.
(4)A term is unfair if, contrary to the requirement of good faith, it causes a significant imbalance in the parties’ rights and obligations under the contract to the detriment of the consumer.
Debt collectors have no power. You can argue its unfair and not enforceable
Can I clarify anything for you about this today please?
Yes I would.
Does that clarify?
If I could ask you to rate my answer before you go today, otherwise the site does not pay me for the time spent with you today. Thank you in advance and good luck!
