Call centre Bad attitude, bad service

I called ccd couriers on Friday the 22nd of Feb if I am not mistaken. The lady I spoke to had a coloured accent and she had a very bad attitude. Anyway, I was updating them that I changed phone numbers because I am still waiting for them to deliver my FNB Premier Cheque card. She rudely said I must call FNB and change my number with them and ccd will hear from FNB. I dropped the call and I called FNB and they changed the number. Called back again to ccd couriers and I found the same lady, told her that FNB has changed my number and can they deliver my card as soon as their system updates the information and all was arranged. I called them again on the 28th of Feb and asked where is my card and they said they sent me an sms that they were coming on the 25th and I was not home when they came. And therefore they cannot deliver because I have reached the maximum number of deliveries. And I asked to which number was the sms sent and the guy called out my previous number. And I politely said that number you are calling out no longer exists and I did call ccd to update my new phone number. And the guy said he doesn’t know what happened then but he was going to check and get back to me and he never did.
