Mobicell headache

The problems started when I purchased the Mobicell phone with tthe accompanying MTN sim card on December 24.

1. My new Mobicell phone,s battery lasts for less than a day if the phone is used not much. A new battery should last for more than a day. The lady at the Mobicell call centre says the phone needs to be taken back to the shop where it was purchased and booked in for the battery to be checked. According to the call centre this will last up to 7 days. According to the call centre there is no workshop I can take the phone to be checked. I have to book it in.

2. It took 3 days to connect the phone to the internet because the Mobicell phone cant receive the internet settings send by MTN. To solve suchg a problem with the non existing service of MTN seems to be impossible.

After strugling to get the Whats app online for FOUR days I need to take the phone back to the shop I purchased fro another 7 days!!!! What do I do if Mobicell states that the battebry is fine and is only suppose to last for a few hours? The issues with the Mobicell phone seems to be never ending!!!!!!!!!!!!!!WHY ON EARTH DID I BUY A MOBICELL!!!!!!!!!!
