I have had the 2 lines for $60 for Seniors for several years and had no intentions of changing it. I recently went to a T Mobile store to purchase a replacement phone when my existing one quit working. The clerk sold me a phone and I was also given a tablet that was advertised as free. When I got my next bill, it was considerably higher and 2 more lines had been added. When I complained, a refund was given and my plan was restored to the original $60 per month/2 line plan (plus small monthly payments for accessory, etc., purchases). When I got my last bill, my account had been automatically drafted for around $70 more than the previous month when my plan and charges had been corrected. Please advise.
