Poor service from blue label connect

I took a contract cellphone with Blue Label Connect in my 2024. It delivered to me same month. After charging it and putting everything together, and activities the SIM card, I discover that the loud speaker is not working. I called blue label connect costumer care to report the factory fault on the phone. They promised to come collect it for repair or replace if needed. But it never happened. It's been 3 months now and nothing has happened I keep getting the same response "we coming to collect it". I am calling them every day no action taken but they collecting money from my account. To top it all one of the consultant told me to find the coria company and drop off the phone there. I even asked them to counsel the contract but they asked me for R6000 for ending the contract. Then they said if I am not paying that money they will keep collective the money from my account while I am sitting waiting a useless device. Please be aware of blue label connect with their poor service. Advice me what to do now.
