Worst experience ever!!!!!

I took my phone in to Trade Route Vodacom on the 8th February to have a cracked screen repaired. The phone arrived at Vodacom Alberton repair center on the 15th of February. I have since been calling weekly to find out when I will get my phoned back and a month later no one can tell me why it is taking this long. Initially they said that the phone will be fixed within 2-3 working days and I am still waiting and they keep saying they are waiting for parts or that it has to be further assessed. The service from Alberton repair center has been the worst experience ever.
