Momentum Multiply has no problem with ***** third parties

I was with the Momentum Multiply because one of their partner gyms GoHealth, gave 100% rebates. On 5 December, I received a promotional email from Multiply saying that GoHealth will no longer be a partner in 2020. I emailed Multiply, and they confirmed the GoHealth partnership termination. I contacted GoHealth on 11 December to cancel my contract, and they advised that a calendar months’ notice is required. This was unfair because neither GoHealth nor Multiply gave me adequate notice of the changes, thus I in turn couldn’t terminate my contract in time, as required by GoHealth. GoHealth blames Multiply, and vice versa for the lack of timeous communication. Multiply says ‘it’s between me and the third party’. I took the loss and carried out the contract to the end, but now the *****ed GoHealth won’t pay me my December rebate, even though the GoHealth/ Multiply partnership ended at the end of December!

True to form, Multiply is now just ignoring my emails and GoHealth just couldn’t be bothered. I want to know as a ‘reputable’ company, if Momentum Multiply enters into partnerships with other companies, are these companies not vetted? Do they not sign agreements with Multiply that need to be adhered to or can any old company just promise Multiply’s customers anything they can think of; if they don’t deliver, then Multiply simply looks the other way and says ‘it’s between you and the company’? What a way to throw your name away, Momentum.
