disgusted with lack of communication

I have content Insurance with std bank and recent my mobile phone was fixed via a 3rd party it was outsourced through standard bank,

When my phone returned it was missing *****s and the replacement/repaired screen was so loose it could just pop out.

When popping into I store – they could not assist me as my phone was fixed by and approved I store , instead by some company std bank outsourced the job too….

Now std bank says they have to be given a chance to fix the error on my phone so last week I called and they arranged to collect the phone Monday, the courier guy never pitched up nor did the 3rd party even call us so apologise or advise of any delay they had,

Friday they called my husband saying they will collect Monday, they collected the device and again its gone to a different 3rd party as the 1st.

Now Firstly I have a Iphone and its only supposed to be fixed by and approved iPhone repair centre, according to my Understanding Samsung electronics’ is not approved iPhone repairs.

No I have been without my phone for a week, no apologies no lack of communication and again no client services.

Now I do not want this phone anymore and want to be paid out and buy a new handset as the people you outsourced the job is is pathetic …. And its not fair that if the phone’s screen broke it came back with a faulty button and missing *****s as well as a loose screen that I should have to endure any more hassles with a handset if I have it insured.

I would like this resolved immediately as I would like to know when I will be reimbursed to purchase my new handset.
