BAD CUSTOMER SERVICE

Hi , I have my cellphone covered under his insurance which is 24Hour mobility . On the 15 August 2019 they came to collect my device to go to repairs as it had a broken screen . I keep on calling them everyday and they keep on telling me that they will be in touch with me and the repair guys are done but i am still without a phone .. i call daily and they do not even seem to care and do not keep their promises because when i call today they tell me a different story from the previous day . Now i am tired of calling them and want my device as i can see they are a **** , i will go and fix it myself as i know replacing a broken screen cant even take 3 days . Please bring back my phone and cancel your damn insurance .
