Poorest service in the history of customer service hands down

Cell C has by far given the worse customer service that I have ever received in my entire life so 1st my mom has to wait 6 months for a device repair no feedback, no apology, not even an update as the process goes along then I come to this platform log a complaint it sets things in motion my mom gets contacted device is ready for pick up. The mere audacity of Cell C to return a broken device back to my mom saying if you have 2 devices only 1 is covered by insurance meanwhile all the installments that goes off my account and the monthly emailed statements that I receive from Cell C shows that insurance for both devices is deducted every month this is unacceptable people's hard earned money.Also if only 1 device was insured why was the phone with them for 6months so in 6 months time nobody could pick up this device wasn't insure. I will not leave this here if we have to take it further we will. This contract ends this year I wouldn't advise anyone even attemp to go there. Assistance is required either way my money back or a new device.If needed ill send whoever the monthly statement that shows a deduction breakdown. 0 RATING IS AN UNDERSTATEMENT. I've never been so disappointed and dissatisfied with a company especially the way they've been treating my mom like a beggar or like she's a nuisance meanwhile they don't forget to take 1 debit order from my account the past 20 months.This is unacceptable.
