My Multiply Reward doesn't work anymore

I have called and emailed Momentum Health since January to re-link my rewards programme to my Multiply profile. Every time I speak with somebody on the phone they tell me to hang up and my profile will be linked in 15 minutes. This has happened on 7 calls and they no longer respond to my mails on the same topic.<br> <br> I cannot do any online assessments or see my points on Multiply so I'm missing out on so many benefits that I could have by improving my profile rating. <br> <br> I could do all of this in 2014 and my wife's profile is still fine even though I pay for the account. Why has mine changed? and why can nobody fix it??? so frustrated.
