Optimum

Dec. 18 I bought a new tv for bedroom, and realized the old scientific atlanta box was no longer up to date for new tv, ie. Fuzziness, and not working properly248... I called optimum and after 6 or so requests they said they'd mail me a new box... They omitted to inform me I would need to return the "older" out of date box... I got rid of old box, as I was under no impression they would need it..., it was broken and plastic pieces were missing, it was at least 15 years old... I was fine until the bill came and they claimed I must pay them a surcharge for not returning box... I was surprised and didn't pay them for several months... They then threatened to shut service off unless receiving 20.95, so I went ahead and paid it., I believe in march 2019... I got my new april bill and its' approx 26 dollars more than my regular "older bill" that I paid them for years, actually 227.00... I called them about why 248 dollars and they are billing me for 4 boxes and I don't have 4 > >? I have gotten no where w/ them since. Please help.
