Unprofessional service

Mr husband opened a game card and used it once. RCS then blocked the card. When he called the call centre, he was informed that an sms had been sent to him which he never received. On further investigation we found out that they had a cell number on record that he had used more than 10 years prior and if you call the number it says it does not exist. The call centre operators are very unprofessional and throw the phone done if they are not happy with what you are saying. When calls are dropped they never call you back to sort out the problem. You get told different things by different agents, my husband has decided to never use the card again and to close it once paid off. A good customer lost because of very bad service.
