unqualified managerial experience

In march 2015 we had taken our handset to markhams in southgate for repairs only to find out a month later that the manager had not sent the device for repairs and it was still within the store, a week later the manger had sent it to the vodacom repair center and informed us that the phone could not be repaired when we went to collect the device we had notice physical damage on the device and no one was prepared to claim responsibility. The phone screen was cracked and the phone was in terrible condition, we were then reffered to vodacom alberton and told that if we took our phone there personally it would be faster than markham sending the phone in, the manager at that time of the store assured us that he would look into this matter and assured us that the device would be replaced as it is still within the warranty period. we were given a replacement device, in feb this year the device began to give us problems and we had taken it back to the store,5months later we are told the simreader is damaged due to physical damage and should we accept this repair it would cost us R3500 to replace. the "new" manager of the store doesnt have the decency to contact us and he has numerous staff phoning us to attend to this matter. The manager of the store has prooven that he is uncapable of managing the store as this matter took 5months to resolve. I am disgusted with the service received from vodacom alberton new market mall and i will never purchase a vodacom phone again
