Call Center is the pit of depression

We recently took out the GoSolr System and took advantage of a promotion deal, which would negate the admin cost for installation. At this time, we still have this account being requested for payment, still on the app and still getting notification messages to pay it as soon as possible. Have contacted the call center twice, mailed the *** and *** more than once and still this invoice is being displayed and being requested to be paid.

How hard is it for the finance and promo side to come together and have a plan to prevent this from occurring.

Because of this invoice not being paid, I cant get the Gosolr app to work and therefore have no control or knowledge on the system workings. Numerous calls to the call center have advised that they will contact the relevant department. Please try reregister or simply I dont know answers have been provided.

Please I beg, can the Invoice issue be dealt with and removed from my account so that I can at least get the system Im paying for working to start the promised savings.
