Mrp mobile poor service

I have 2 contract with mrp mobile.july k asked them to give me the total amount to close of the accounts ,they did I paid off but they still deducted money from my account. Said I should give them 30 days notice,now the notice it's over, it's even hard for them to give me a confirmation letter to say the accounts have been paid in full and closed...poor service and incompetency with this company.
