Virgin Active Cedar Square Poor Service

I took out a membership with Lorraine from Vigin Active Cedar Squre, I have paid my joining Fee to date I have not received my tag or bag. Lorraine does not respond to whatsaps or calls. I phoned the branch and they too does not return calls almost a month later. They hastle you to pay and complete forms etc but don't deliver. Surely the contract is null an void due to unfulfilled agreemens.
