My phone has been in for repairs for 55 days

Took my Samsumg cellphone to samsung store in Broklyn Pretoria for repairs on the 17th of March 2015, after 2 weeks they phoned me to say the proof of purchase was missing so i had to resend it otherwise they cant carry the repairs. The phone had a problem with the charging port, On 20 April 2015(after 32 days) i got the phone back. The charging port got sorted but the microphone got broken in the process, what happened to testing a device before sending it back.On the 21st Of April i returned the phone back to sort out the microphone, up until today ( 23 days) still no phone.<br> <br> Samsung makes good products but i regret owning one because of the bad service, i have been without a phone for 55 days and yet i am paying for it monthly.
