Southwest Credit Systems, L.P. Debt Collection Complaint

Southwest Credit Systems, L.P. Debt collection department,

Other (phone, health club, etc.) Cont'd attempts collect debt not owed Debt is not mine New Jersey

My complaint is with - - service. I was under contract with them to pay $120.00 per month for bundled service ( TV, internet, phone ) through -/-/15. This past -, - changed their billing system and, because of a glitch '' in the new system, I began to be charged $210.00 per month. I have made repeated attempts to resolve this issue by phone ( over - hours on the phone ) and in person but have not been able to get it resolved. I grew so frustrated that I cancelled the service and tried to calculate what I thought I should pay. I forgot that the monthly bill is paid in advance so I actually have overpaid - by more than $100.00. However, because of the billing system problem, - continues to send me a bill for $25.00 and just sent this amount to a collection agency. I have continued to call - to resolve this issue ( ticket # is - ) and been told several times that a supervisor will fix the issue and/or call me but none of their promises have been kept. Meanwhile, my credit will be affected by this since the bill is now in collection.
