Bad customer service from cellc

I got a very bad experience with Cellc that I receive while claiming my Phone. I lost my phone on the 16th /08/2022 it was on a sunday. Then on the 18th/08/2022 I blocked the phone and claimed but the following week I was told I must write a motivational letter why I claimed late. Imagine late how because it was not even 24hrs. Remember now my business is suffering but am paying my installments nicely but today when I need assistance for what I pay but service dololo.I gave them everything they need and they are even lazy to check the documents now they requested wat cellphone I was using in the phone but I already sent everything including the number. That's the reason I won't upgrade my contract and I was about to take an additional line with them so am not doing anything with Cellc anymore. No wonder the company is falling its because of the heartbroken customers. Contact details ***.
