Services suspended after 20 years because credit limit was reduced

My MTN services were suspended this morning due to my credit limit being decreased because of my ability to afford it. I got an upgrade to a higher package the same day my credit gets reduced. I have never missed a payment in 20 years and I have 6 lines in my contract which were all suspended. My children are at the mall and are unable to contact their mother to pick them up or in case of an emergency. On contacting your accounting department it was too bad so sad and eventually they agreed to reconnect me which can take up to 24 hours!!!!!! The later in the credit department was not polite at all and after I got upset she grudgingly helped me and increased my credit limit back to what it was. But now none of my family members have any service. This is extremely shocking and upsetting.
