Incorrect Advice and lack of service

What incredible ****py service I have received from MTN Tygervalley and insurance Guardrisk! I have been misinformed and not provided the proper advice regarding insurance policies after the rejection of a water damage claim neither MTN nor Guardrisk have taken any responsibility for resolving my claim. I am appalled at the service I have received from MTN Tygervalley store, the sales agents are quick to make a sale but unable to provide the correct advice with regards to insurance policies with their third party Guardrisk. After taking out a contract with them and being in the store for 3 hours setting up the new device the sales agent put a vodacom sim card in the phone and never informed me that we would have problems with an insurance claim since then I have requested assistance from a manager after speaking to Aiden in the store and have still not received any assistance from them. The insurance department directs claims to Guardrisk and even they have not assisted me in this process. I was informed by the sales agents in the store that it is the responsibility of Guardrisk to inform me of their policies and have not received any phone call, sms, email confirming any details and now that I need to claim neither MTN or Guardrisk have taken this matter seriously. It has now come to a point where I as a customer am not only dissapointed at the service I have received but I am now forced to take further action in order to protect myself from paying for a service that I am not receiving despite having this affect my reputation.
