Switch from MTN.

When Nashua stopped their mobile service I was moved over to MTN. On 10th May I got a message to say I had exceeding 90% of my credit limit.. Tried calling them but eventually had to give up. Yesterday I got another message to say I had exceeded my limit and my service has been suspended. The credit limit must be a thumb suck by MTN because my contract has been paid on time by debit order for 15 years.<br> I challenge you to try to phone their call centre. Total waste of time. Imagine a telecommunications company and you can't get through to them. Eventually went into their shop in Woodmead. Lady there phoned them but gave up after 15 minutes. She sent them an email at 11:30. Still no response. <br>
