Wait for Ever with this lot!

I have been asking you to contact me back for a week now, no response. I had to take my tyres off at Tiger Wheel due to you declining the transaction.. Which i find hard to believe as the account is in Credit. I was on hold for 15 min with your call centre, no one answered. I tried the self help route, there is no help. The email address sends me back to self help. The self help says the account is in suspense and to phone you, which as said previously you do not answer. Social media just says someone from the relevant department will contact me. But contact me when!!!!!!!!!!!!!!!!!!!!!!!! Things have to be done, and you are making me look like a ****** fool. When are you going to be phoning me back to sort this account out!
