Very bad severe from cellc. I don't think cellc have any customers service experience

I sent a complaint on this group about the bad serviced from cellc. I sent this complaint on the 9th of February 2021. On the 10th someone from cellc social media call me and I explained the reason I lock the complaint. The lady sad that she will get back to me and from that day no one from cellc got back to me, I want to cancel my contracts (3)with them I cant go on like this with a company that don't look after there customers.
