Poor customer service

My bill increased $50 and I paid the bill. I reworked my plan & was promised a $50 credit. That never happened and the next bill came and I paid that too. I called and was told pay the bill and since the billing cycle has passed you will get a $100 credit on the May bill. I got the May bill by e-mail and the credit is not applied. Month after month its one lie after the other. I've been a customer for 25 years and your taking advantage of me thinking I wont switch. I have the ticket number for my issue and its [Edited: "Personal Information"]. I do not want you to charge my credit card again with the $100 credit. You can get my phone number from the records and I wish a phone call. Everytime I call I'm told no Supervisor is available. Hope to hear from you soon
